My sister says I'm ugly - is she right?

Dear Advice Girl,

I’m extremely self-conscious of how I look, and my sister rubs it in and says I’m not as pretty as her. My friends beg to differ and say I’m very beautiful. I don’t know who to believe...please help!

Signed,
   Ugly

Dear Ugly,

Believe your friends. You’re pretty.

How do I know? Because, like, 95% of being beautiful is believing it. (The other 5% is stuff like showering regularly and not having any open wounds.)

So if you know you’re hot, and if you push negative, hurtful thoughts to the side, you’ll be the hottie your friends already know you are.

(BTW, forget about whatever your sister tells you. She’s being a majorly insecure bully, and you can tell her I said so.)
