That's what you think. You're just blinded by the infatuation.
When you ask her out she will laugh in your face and tell every other girl in school about the loser who asked her out. Everyone in school will know how much of a fat loser you are and you probably won't have any more friends after it. And it won't stop at ridicule either, soon the intense bullying will start (you may even get cyber-bullied!) and death threats will be posted in your locker. A couple weeks later a bunch of guys will gang up on you after school and kick the stuff out of you, tying you up with rope and tape and throwing you in a dumpster behind the school to sit all weekend. No one will know where you went, an Amber Alert will be issued, but they won't find you in time. Come Tuesday morning the garbage truck will come to collect the bin. As the compactor door closes in on you, you will regret not following my warning.
