a friend of mine recently broke up with her boyfriend.

they've been going out for the past two years, were in love, however they broke up and got back together many times. He's cheated on her before (while intoxicated), however she always took him back.

Now they've broken up for good (he broke up with her) and he keeps telling her "I want to want to love u and be with you" and while she's trying to get over him, he isn't letting her.

What should I say to her when she talks to me about it?

(btw we are juniors in high school, this isn't like THAT serious of a relationship)

there were 3 guys, poop, shut up, & manners.
One time they went on a walk and poop fell in the pond.
Shut up went to go get the police, and Manners stayed with Poop to help him out. The police asked Shut Up" what's your name boy?" and he said "Shut Up!" then the police officer said" where your manners?" and Shut Up said, " down by the pond picking up Poop!"

How come you are more likely to see a mirage in a hot day rather than a cold one?

Yesterday me and my friends were playing Halo for eight and a half hours and this morning I woke up with soreness in the front of my head and the back right of my head, but it wasn't on the outside that it hurt. I haven't played halo with them in quite some time either.

This made me wonder whether the brain worked just like every other muscle in that it got sore when used vigorously like in a workout.

So, does the brain get sore when used in such a way that can be considered a workout just like other muscles in the body get sore after a workout?
