I only have 12 contacts on my iphone?

My mum said i was allowed an iphone for christmas but only if i'm actually going to use it to text people. I was wondering.

i have 5 good friends i would always text and phone
5 friends i would text aswell, not as often though
and my mom and dad, for when i have to contact them

so all in all i would only have 12 contacts. Is this weird?

Added (1). Thank you so much for all the nice anwsers! I was worried there was going to be a bunch of bullies saying i was a loner and stuff.xx.

How to ask someone to be invited to a social media group chat?

I never use a phone. What I do have is an iPod touch which I use for everything that an iPhone does (when there's Wi-Fi around), and generally I'm being considered as someone who no one really contacts through social media or texting or anything. And now amongst my group of friends, a good chunk of them are all in a large group chat on WHATSAPP, and I always just dismissed it as one of the perks I'd always miss out on due to my lack of enthusiasm for smart phones. But these group of people in my group are getting closer and so I'm starting to feel as though I'm a little left out, they even have private jokes now which I'm not in on.
I understand that I could easily get Whatsapp on my iPod, but what I'm wondering is: how do I ask my friends to join their group chat? I know it sounds like a stupid question seeing as they're my friends and all, but right now I'm really considering how I would invite myself to this group they've had for ages without sounding awkward or desperate?

When will the iPhone 5 price drop? - 1

The highly anticipated iPhone 5S will be unveiled tomorrow, September 10. I'm interested in buying a new iPhone 5 but only when Apple reduces its price. Will the price of the iPhone 5 drop tomorrow, when its successor is introduced? Or will it drop when the iPhone 5S is available for pre-order or to the public (rumoured to be in retail stores September 20)?

Does anyone remember how it was when the iPhone 4S's price was reduced?

If I can't add someone to a group chat on Whatsapp, does it mean they blocked me?

I created a group and tried adding someone I know to the group, but when I click on "Add participants" I can't see his name on the list. He is added as a contact on my phone but I can't see his status and when I click on his name it says "Invite them to use Whatsapp" I know that this person owns an iPhone so he already uses Whatsapp. Is it possible he blocked me (we never talked to each other on Whatsapp before, so it's unlikely) but it's just that his phone is switched off right now?

Added (1). There are many slots available in the group, and I'm able to add other people, so the problem is with this particular person.

My iphone 4s is losing battery extremely quick?

Lately my phone has dropped battery percentages so quickly. I let my phone charge overnight and it was 100% when I left my house this morning. On my way to work, I used my phone to play music in my car (via bluetooth). When I got to work at 9am it had went from 100% down to 73% in just 45 minutes.

Now, it is noon and my phone is on 18%. I haven't used it at all since I got to work this morning besides responding to a few text messages.
