Need to rant on a few pet peeves

I've realized there are two things that bother me a lot: Tardiness and ambiguity.
Tardiness: I think it has to do with a "let your 'yes' be 'yes' and your 'no' be 'no'" business, or I'm just an incredibly uptight, anal-retentive Westerner that is more concerned about the clock than the time, but, I think because I tend to be on time (or early) to a fault, it irks me all the more. I think if someone tells you that they will be at X by such-and-such a time, and then are consistently late, it only communicates (to me) that my time is less valuable than theirs. It, in fact, makes me feel that they don't value my life and ways that I use it.
Ambiguity: See above. I think being unsure and wary of people's motivations or inclinations becomes exhausting. I wish people were a little bit more up front about how they really felt about things, or would not try to be nice for the sake of harmony.
That's it. Just needed to rant a bit.
