All I'm thinking of is this: My last option, as in when I'm really really desperate, is to sign myself up to the Eastern Standard Tribe.
I think I've bumped into too many people speaking in gross accented English at favorite coffee shop corner and I'm just not used to it still. Everytime I run into them, in tribes and speaking very loudly, I cringe.
But if things get out of hand, it's either beat them or join them. You know I don't like that last option.
