I'm chatty and nice

And for some reason people get really upset with me. Not all the time, but on occasion I get the boss of all grumps who is really passive-aggressive/aggressive.

I try to make sure no one gets upset by giving compliments and passing jokes while I'm not doing (EDIT) anything (i.e. whenever I'm in transit, during the epilogue of an epic play, or whenever my team has a good success/kill/failure... you get the idea). Its never when I'm playing or during a serious moment, its always when things are chilled out or surprising.

My question: Are people really just so grumpy that they gotta blame the loss on the happiest person on the team? Especially, this was last game, the 10/8 leona compared to the (EDIT: no names)? (iirc, my numbers may be off)

After game I found out how mad he was (I afk'd after we lost because of RL) when he said we lost because I was so chatty.... =(. I'm just kinda emotional when people hate on me, hard to deal with it.
