Recently I was invited to a casual games night at a coworker's place, and near the end of the evening there was a group of about 6 of us (a couple coworkers of mine, a couple friends of theirs, my partner, and I) sitting around chatting. The topics were very interesting to me (think the future of humanity and AI and such) and I enjoyed listening to the different perspectives people had, but I also wanted to jump in and contribute my own thoughts.
I tried interjecting a couple times, but it seemed to go unnoticed and/or someone else started talking at the same time, so it didn't get far.. This isn't a new problem for me since I am soft-spoken1 and can take some time to gather my thoughts, especially with conversations like that. However it usually comes up in work settings where I have other options (e.g. getting the attention of my team lead, or following up later).
Part of the problem may have been that I was visually blocked off from a couple of the most active participants, since I was at the end of the table and the person next to me tended to lean in. (Maybe I need to adjust my body language too?) The conversation was also kind of fast-paced, so by the time I had formed a comment, someone else was likely to start talking first. I didn't want to interrupt them or return to an old point just to say my bit once the conversation had moved on.
Overall, I was at a loss of how to signal to the group "hey, I have something to say too!" and have the floor without feeling like I was disrupting the natural flow of conversation.
What tactics could I have used to insert myself into the conversation?
1: Please don't tell me just to talk louder; everyone heard me fine earlier when we were playing board games, so I think there's more to it than that. I can accept that talking louder is a part of the solution, but I'd really like to know what else to try.
