How to to appear offline completely from Facebook on iPhone?

I already turned off my "online" option for messenger but I don't want certain people to know I've been online at all browsing through my newsfeed, liking posts etc. And it show what time I liked a post or shared something. Is there a way to stop Facebook from showing a time I like/share anything on Facebook from everyone or certain people using an iPhone? I read a different way online to go to friends and select "certain people" to keep from viewing that but my phone doesn't show that selection on the app or safari. Any help? No links if possible. If there's a simple instruction to do it that would help out the most.

My iPhone won't disconnect from AirPlay, what do I do?

Basically, I always play music off my phone s speakers before bed but when I went to do that tonight, it was paired with AirPlay - which by the way I've never manually connected it to. We have an Apple TV but like I said, I've never actually connected to it before let alone today. My phone won't even give me the option to disconnect from it. I tried restarting my phone and everything, still nothing. Is there something I can do to fix this or is my phone just glitching on me? It's and iPhone 4s and I have iOS 8.

Kids Clothing? Am I a bad parent?

My Two kids (Zoi aged 13 and Zahara aged 15) do wear brand named clothes and this one mom got all angry about it to me and said I should buy them walmart clothes.
now I buy them brand name clothes like (Uggs, Lulu lemon, Hollister, wet seal) you get the point but its usually all on sale. My kids came up to me one day and had their birthday money in hand and told me "Mom we will buy our lulu lemon pants and uggs from now on since we want to pick out what we want" and I was happy and joyful and grate full. Now I go to Hollister and my kids pick out things that look like its 39$ but the amount comes to be $9.99 see, I never taught them to look in the clearance but they always tell me "Mom the clearance has cute things" and I got them both skirts for 3.50 each. Now I don't mind paying for some school out fits for them and when we go to wet seal we do the wall deals of 5 things for $20 and then they can pick out ONLY one item that's not on sale but reasonably priced, and I don't mind it.
Now I wear Lulu lemon and my oldest likes the jackets but I didn't want to pay $65 so she looked and found one for $30. I still shop at Target for clothes in the teen section since the tops are comfy and some of the shoes are to die for. But I did recently found at Fred Meyers they had converse on sale, and both of my kids are 3's in kid size shoes and they both wanted white ones and FredMeyer had a half off coupon so I grabbed the last two that were in size 3 and surprised my kids. Am I bad?

Added (1). Also to add, my Husband and I recently switched our old phones (Iphone 5s to iphone 6s ) and gave our old 5s ones to our kids since they had the 4S for about 3 years now and they love the 5s ones better than the 6s which i'm glad they aren't bad about them. They do not beg for things and when were out and about and something on sale I usually get it if they were good in school or did all their chores.

Jailbroken iphone cydia messing up?

My iphone 5s is currently running the first release of ios 8. I jailbroke my phone back in may. Anyway, recently my cydia has been messing up and often does things like this. When i try to remove a tweak or download one, it tells me the file can't be located and i need to manually fix the problem. Difference is, in the installed tab on cydia thw tweak is red and has a red negative sign. But in the search tab, when i look up what i'm trying to download its lit up blue with a blue plus sign. I'm considering removing my jailbreak because of this, updating my phone then rejailbreaking it if this doesn't stop. But, if i do that i will loose all of my music i have via linktunes. So, my questions are
1. Why is cydia doing this?
2. If i were to remove my jailbreak, is there a computer program i can download to remove all of the mp3 files off of my phone where i can later reapply them on my iphone?

Is god fictional? Along with heaven and hell?

Basically, verizon called me today telling me i have an outstanding balance of $497.94
My bill is usually only like $116.00
I don't know why or how it got to this ammount but it did and i'm scared. I do NOT want my parents paying this much for my phone bill. Although i'm 13 and don't have a job. I'm trying to find a way to work this out so my parents don't have to pay this price all at once. We arent having any financial issues or anything, its just thats a whole lot of money for 1 phone bill. Btw: i have the Iphone 5s like i said through verizon as my carrier. I have no idea what to do and i'm afraid to admit this to my mom. What do i do?!
