Man, I swear to god, if you tell me three times to show up to your stupid fucking bar show at 8:15, for an 8:30 start, and to post about it, and share about, and tell people about it, and then you show up at eight-fucking-forty-five, for a show which you'd always known the whole entire time wouldn't start before 8:45 (never at 8:45), I don't give a fuck.
Ask me in that tone, feigning and faking caring, "oh, do you have somewhere else to be?" [comic-speak for "do you have another set and have to go up early?"] Yes, I have somewhere else to be. I always have somewhere else to be (other) than waiting for your stupid fucking show to begin, waiting on account of making/having made decisions based on misinformation. Your lying to me or the ethics or permissibility thereof is not conditional on my having another stupid fucking show to go to or not.
[Even in Grade 4--leave the fucking kids behind who didn't show up for the bus on time. They didn't want a Ski Day; they shouldn't get a Ski Day. Every day, every time waiting for the one stupid student, everyone (else) having to wait and be punished for their respecting others. No one learns/has to learn anything in this society (a bit much), no one cares.]
Anyway, if you bitch ("bitch")/complain about it enough (i.e., explain it to him in sufficiently simple language as to why he's being a ******* *****/entirely thoughtless), then you'll/may get to go home early for having been put up first so he doesn't have to deal with the reality of his/the situation. (Calling people on their shit is important, as it makes them feel uncomfortable, and they won't want to feel uncomfortable in future.)
There is so much disrespect. This is one of the ways.
(It does not matter being put up first. It matters nothing. Accepting, and understanding the fault, the wrongness is what counts. Articulating the acceptance and understanding is what counts.)
