I'm still pissed off about having my long weekend plans blown to shit

So much for looking forward to the big Labor Day weekend party my sister's gonna be throwing — the last one before she closes her pad for the season. But I'll have to attend an event I don't even want to go to one day and then head someplace else another day I definitely don't want to go to. All because someone with no concept of scheduling couldn't keep their shit as planned, so now all mine are fucked because of their cluelessness. Fun times.
