TIFU by trying to get out of a city bus

This happened a few hours ago. I went to a different town for a day with my mum and we were in a city bus. It was basically empty apart from us, so we sat down. Anyway, on one station my ex got inside with some of his friends (I can't believe my luck to have met him in a different town). They were standing across the door, so they looked directly at it. After a while I had to get off so I started to go towards the exit while the bus was still moving. But I guess I got up too quickly and I saw black for a couple of seconds and kinda lost my balance, and in that moment bus made a sudden turn and I hit the wall of the bus. But I didn't just hit it a little bit. You know in cartoons when a character hits the door in a funny pose and the shape stays in the door? The difference between that and me was that this is real life. After that I got up and had to stand there next to them until the bus stopped and mum and I were able to leave. Here's another fuck up (kinda): I turned left instead of right so my mum had to pull me by my backpack in order to stop me, and the bus doors were still open so they probaby saw that too. So yea, I'm never getting up in a moving bus again.

TL;DR: I got up in a moving bus and hit a wall in front of my ex and his friends. Also, this was in a different city to where we live, so I guess I was lucky enough to meet him 100 miles from home.
