I also have a good buddy who's the touchy type & it gets worse when he drinks...but he's pretty harmless so I ignore it...
On the other side, I used to work with a guy who was a pretty good work buddy...it was during my last few days at the job before I left to return to college & he wanted to hang out with me before I left for good...long story short, he kept hugging me...after about the 3rd one, I told him not to do it again...he said "sorry buddy, I'm just gonna miss you so much"...
and then he did it once more...that felt really weird and wrong...
