So, I have a problem with 2 friends who can't be punctual when we hang out. 1 shows up to the agreed time 10-15 minutes earlier. Last time i was just done eating my dinner this time i wasn't finished (bathroom) and he stood outside in the rain for a few minutes. If i arrive to a meeting earlier I just wait in my car. Personally, I find arriving too early as rude as arriving to late. I always say the time, like 8pm. Friend 1 says around 8pm ok. Where I write again 8pm so he gets that it's not too early. 5 minutes earlier or later are OK, even 10 minutes later. But everything ontop is rude.
Another friend i know since a very long time (we alway meet at the same time. we live 5 minutes apart) plans are set for days. BUT he mostly writes at the agreed time that he'll run late (15-45 minutes usually) sometimes he doesn't even write and I'm waiting. Or i arrive at his place, his mom lets me in because he's still in the shower at the agreed time. That's why i also will try to arrive a few minutes later now. When i pick him up per car he is also always running late.
So when we all meet together i get stressed because friend 1 may arrive sooner. Letting me get ready way before our agreed time. Then i wait. If friend 1 arrives we have to wait 15-45 minutes for friend 2, to finally start the game.
I'm unsure how to articulate this or bring it up to them.
