Why is this website full if immature teenagers?

My God! Get a life you lot! Who cares if you've 'got a *****' or 'are pretty enough?'. Pretty enough for what?

Immature idiots! Go and sample life instead of living it through your computer and Iphone screens!

Do you ever just not read messages from guys?

On an iPhone, I've noticed this girl hasn't read my texts. It says the iMessage is 'delivered' but hasn't been showing as read for the last five days. I've sent a couple more because she told me she was going to get in touch when she got back on the Friday from a long drive during the holiday season (heavy traffic coming back into the city).So obviously I'm worried… Maybe she crashed? I don't have her on facebook and there has been no way to tell (she lives five mins away so I cruised by and noticed her lights were on but maybe the flatmates put them on?)

I texted: 'are you alive? Two days after she was supposed to get in touch (after sending her a nice message the day before) but now I'm thinking if she is reading them she probably thinks I'm overly concerned. Do you think she has turned delivery notifications off and is still reading texts? Or do you think she probably is just ignoring them for some reason? I can't fathom it because it seemed like she was really keen to get in touch.

Added (1). So I just sent one today about an hour ago following up the are you alive one yesterday (this is the longest text I've sent the other ones have all been pretty short)

'Just worried because you said you had a long drive and that you'd text when you got back on Friday but there was no message. Worried something might've happened to you… But then again your phone could be playing up! I hope you have a great NYE! See you next year. Call or text when you get this tell me if you have any plans coming up! There's a cool movie showing in the city that's got pretty good reviews I thought we could see!'

I don't know if I'm weird like that?

I count the words to a song using my fingers and if it end in odd ill do it again to make sure it was even and if it wasn't I'll change the phrase so it could be even or then I get pretty weird about that. Also with my iphone i lock and unlock my phone with the lock button to make sure my lock button wasn't broken( a lot of my friends broke their lock buttons so I was afraid too). I have a lot of other things like getting such stress and anxiety over little things and I have to keep on googling it and etc.am I weird lol? Or do you guys do this too?

If someone blocks my number?

If someone blocks my number on iPhone will they still be able to call me if they want to? And will i be able to see their number or will it come up as private? Thanks Oh and what happens to my text, will they receive them one they unblock me?

How to unlock the network on my iPhone?

I have a second hand iPhone which was previously on o2 and then giff gaff (which apparently both use the same network) and I'm on virgin so I want to unlock the network WITHOUT HAVING TO JAILBREAK MY PHONE. How would I do this as giff gaff don't have any shops and the o2 contract that was originally on the phone expired ages ago.
