I've had some bad collab experience too, though most of them were caused by my own mistakes.
Sometimes when introducing the guests, I accidentally forget to introduce one or two people and only realize it after someone points it out.
There have also been times when people were sharing something and I unintentionally interrupted them or talked over the current conversation.
Those moments always make me feel guilty afterward. Since then, I've been trying to pay more attention to these issues in future collaborations.
I hope I can help my guests and friends have a more enjoyable time whenever we play or work together.
