People who assume plans are cancelled if you don't message them on the same day as the plans.
Sometimes I'll make plans with someone. We'll agree on a day, we'll agree on a time, we'll agree on what we're doing.
Then the day of the plan that we had arranged, I will get there at the right place at the right time and they won't show up. I'll wait a bit. They still don't show up. I'll check my phone. No calls from them. No messages from them. So I give them a ring or send them a message: "Hey, I've arrived".
And I'll be met with a response along the lines of "Oh sorry, didn't realise our plans were still on"...
Well, um, neither of us cancelled the plans, so why wouldn't the plans be on?!
"Oh, you should have messaged me this morning to remind me it was still happening" ffs
Sorry just venting.
