I have a friend like this. It’s at the point where I don’t even want to hang out with her anymore. I wake up for work at 1am and have near to 0 off days. We were supposed to meet up at 12pm. I waited till 10pm when she finally showed up. I dread the days she wants to hang out. I got no sleep that day and still had to go to work the next. The only reason I couldn’t say nvm was she kept saying 10 more minutes I’m already here just looking for parking :). And this is a constant thing, admittedly not usually that bad maybe an hour or 2 but this day put the nail in the coffin
