**Take the Tangents** Often during a conversation part of it will remind you of something only tangentially related. Instead of saving the slightly related thing for later (and probably forgetting about it) follow the tangent and then when that runs out you can easily return to the main topic of conversation... The more you split off the less likely you'll run out of topics to talk about, and worst case scenario you can also resort to "What were we talking about before (first tangent you can remember)." For example, say you're talking about a TV show (say Game of Thrones) with your friend, a mention of dragons reminds you of the Anne McCaffrey books you read a few years back. Segue into talking about those (maybe whether or not they'd make a good TV show). If you can find a new tangent before your return to talking about GoT all the better. That way if the conversation lulls you can ask "What were we talking about before the Pern books?" and hopefully revive the conversation.
