I hate it when a person can’t really actively participate in the current conversation topic, so they (indiscreetly) try to change the conversation topic completely. I’m more proactive when it comes to conversing, so if I can’t converse about the current group topic I either wait for the topic to change, or start a side conversation with somebody else entirely, but if you can’t participate in a conversation already happening, then don’t.
Trying to change the topic to suit yourself better is extremely selfish and usually people notice what you’re trying to do, or will go right back to what they were talking about in the first place after a momentary sidetrack. Sometimes you can’t always have your way with things in life, and this is just another of the many things that you’re just going to have to accept. I mean, you could try to dominate the conversation, and wind up being the only person talking, but by that point of time everyone most likely checked out of whatever B.S. you’re talking about and formed their own pocket conversations, not to mention made the mental note that you’re that d**chebag who has to play ‘conversation dominatrix/dominator’ every time you talk, and will avoid talking to you.
