I think Jennifer Aniston is making a mistake going back out with John Mayer, what is your opinion?

I mean she's such a nice gal, and he seems like such a player...plus all those tattoos...come on, i think she can do SO much better...hmmmm i wonder if she is in a hurry to get married and have babies all that, and maybe she is just settling...2. i mean i think Vince Vaughn would be much better for her than him!!!
