On that topic, one of my uncles is a real curmudgeon type... probably the grumpiest mofo I've ever met in my life...
Anyway, I noticed one time that when I disagreed with him, he would make a face... so I started to always disagree with him.
One day I was riding with him playing golf...
This tee box is trash... meh, it's not bad, see I found a spot...
That was the best shot you've ever hit in your life... No it wasn't, it went straight, I wanted it to be a draw
Anyway, that carried on all day, then by the end of the day, he's all, "You f'in disagree with everything I say, wtf I could say anything you would disagree".
It's hot as hell outside.... I think it's nice out here (it was like 102),
... blurted out about 5 more statements in a row (all of which I disagreed with) ...
The sky is blue... actually, that depends on when you look at it (or something stupid, I don't remember exactly what I said).
I had him all tilted out...
Moral of the story...
I do it in person too:P
