IPhone 4S suddenly won't turn on?

I was walking to class, and I used my iPhone to check notifications. It worked perfectly fine. But as I reach my class, I take it out again, and it won't turn on anymore. The screen stays black no matter what I do. I've tried holding down the power button, but the "out of battery" icon doesn't even appear. I don't understand what happened, I definitely didn't drop it, and there's no apparent physical damage.

My iPhone Pushes All The Wrong Buttons?

I have an iphone 3GS and it was working great then all of a sudden I noticed it would be hard to slide the unlock button. I'd have to try multiple times to unlock my phone. It was like my finger was slipping, but it wasn't my finger. Then it would start pushing buttons I didn't want when I text. It's extremely hard for my to text now because my phone will press the space bar or it won't press 'n' or 'u' and so on. Now it opens apps without me touching anything. I've reset the phone, I just tried recalibrating the home button. What do I do because nothing I have tried works. It's extremely frustrating. If you can help please let me know. I'd rather not have to pay out my *** if I can just attempt to press a few buttons to get it fixed. Thanks.

Added (1). I'm not looking for you to tell me to take it to the store or anything of that sort. I'm not ignorant. I know I can just take it to the store and they can tell me the problem. I go back to my previous statement of not wanting to pay out of my *** if I can just do something here at home.

Girl smiling at me. Right choice?

I'm a pretty decent looking guy, not overly handsome, but not ugly either. I was walking towards my house and I was looking down at my iPhone. When I looked up, I saw this girl about to walk past me smiling at me (it was that girly-type flirty smile). I looked away because I didn't want to seem arrogant, but when I looked back she was still looking at me. We had passed each other and I was about to try and talk to her until I saw 3 of her guy friends giving me sus type (sus as in weird) looks. I'm no p**sy but I really wasn't looking for a potential fight so I decided to let it slide on the slim chance I may see her again. Do you guys think I made the right choice? Should I have just tried my luck and approached her?
