If you're at an office party or gathering where you don't know a lot of people, it can be hard to get yourself into a conversation with a group, especially if you're shy. Reddit user brothelwaffle suggests using the same practice you'd use for your business: supply and demand.

The idea itself is simple:
Listen and figure out where the demand is - what does the group want to talk about? What are they knowledgeable about?
Figure out what information you are able to supply the group.
It might seem intuitive for the common extrovert, but if you're more introverted or socially awkward, it's a great way to test and ensure you'll be able to participate in a discussion before dropping into it. If you're surrounded by people who don't seem to share any common interests, it might be best to ask a few questions and nod politely.
