My experiment had yielded three results so far.
1) duffer is insane and talks way too much
2) mp team mate/ opponent just naturally follows suit and the chat becomes far more friendly and fun
3) mp team mate/ opponent respond normally with abbreviations
Today I may get my Christmas wish and I can't yet decide if I'll continue this experiment or not in my upcoming match with some folks I've been wanting to hang out with and play for quite some time.
I'll probably blab with words as I'm clearly #1 :)
