The Packers must feel like Favre is like that girl that breaks up with you because they are bored with the relationship or want to see what else is out there. Then after a couple of months they realize they were happy with you and they want to get back together.
Well the Packers should do what I should have done when this happened...tell Favre to stay the hell away from them, they don't care about him anymore and let him know that they've moved on with a younger chick named Aaron.
