It's one of those things where, after awhile, you really stop caring about people's good intentions.

The first time someone steps on your toe, it's all cool. When it happens again, immediately, it's irritating. When it happens again right away, you don't care much whether they're clumsy, inconsiderate, malicious or ill, you just want them to stay off your %$@#* feet!

I've seen that puzzle clueless whitefolk (as distinct from 'all whitefolk') time and time again. "Why so hostile? I didn't mean anything?"
