Men Are Dumb And Jerks

Okay, men, what is it about keeping your "rep" and saying something rude in public, then something extremely sweet in private!? Is there something programmed into men that make them act like a jerk in public, but then switch it for private? And i know the whole excuse, that guys are mean to the women they like, but some things just go too far.. I could do without the comment from this morning. Okay, I'm moving on now.
