Does anyone else do this? This is something I've realised and I've consciously tried to correct myself and not do this anymore.
When I'm with a group if I have something I want to say (even off topic) I try and barge it into the conversation even if people are still talking. I really want to get out what I have to say.
What I do now is that I tell myself to wait for a pause or a lul in the conversation before saying my piece.
