You know, the I-really-shouldn't-be-angry-but-I-am-anyway angry?
For example, I get irrationally angry when I hear about great stuff at Trader Joe's or a great sale at Urban Decay. I'm Canadian, so those just feel like a slap in the face of shit I can't get/ship here.
BUT, I really shouldn't be angry. People are talking about their lives. The majority of people here are American, so they are going to talk about their American lives. It would be silly to expect everything to be Canadian-friendly.
What pisses you off for no good reason?
