Girls are a sensitive human species. You can say everything right and still be wrong. We don't mean to be crazy, or overly emotional, or excessively sad, or overbearingly happy... but that's just our human nature. There are a lot of things that can tip us over the edge but some are a thousand times worse than others. To avoid turning that beautiful, smiling, angelic face into the devil in disguise, don't EVER- and I mean never- say the following things to a female:
1) "You're gunna eat all of that?"
Yes, actually I am. And just because you brought it up, I'm going to order fries on the side, too. 
2) "You look tired."
Maybe that's because I am? And maybe you should try NOT to bring to my attention the fact that my hair hasn't been washed, nor my makeup done. I looked in the mirror this morning, I freaking know.
3) "Don't take this the wrong way, but..."
Oh I'm sorry, but how else am I supposed to take it now?
4) "Are you wearing that?"
Oh, no! I just spent all day worrying about an outfit, trying on a million things, and I figured I would just put this lil' number on for fun!
5) "You remind me of my mom."
Thanks so much! I was really hoping you would compare me to your primary caregiver!
6) "Calm down."
Yes that will help. As I'm freaking out, "calm down" is really going to make everything feel so much better!
7) "Is it your time of the month?"
No, but it might as well be now that you said it.
8) "It's not you, it's me."
Good one. Did you come up with that all on your own? Because, yes. Clearly now, it is you.
9) "Your friend is really hot!"
Oh my gosh thank you so much! That's the best compliment anyone has ever given me!
10) "How much do you weigh?"
Oh you clearly know, only like a thousand pounds! But thank you for bringing the most uncomfortable topic of conversation to my attention.
11) "Didn't you have that outfit on yesterday?"
Yes, I did. It's comfortable and cozy and last time I checked, my hygeine was none of your concern.
12) "She's just a friend."
