Guys have just as much feelings as girls.
A lot of people think, "Oh they're guys. They can't cry" "Don't show weakness" etc etc. Yeah well, my dad always told me if you ever see a guy cry, know that he's broken.
Now, I fully believe him. At lunch, one of my guy friends found out his girlfriend had cheated on him.
In our career class, he came in literally crying. They [him and 3 of his closest friends] came in late and ignored the teacher's lecture.
If you ever see a guy crying, go hug that boy.
