Do you all actually enjoy conferences or is it just me pretending

Went to my first meetup last month specifically to network and spent most of it near the snack table doing math on how long until I could leave without it being rude. Talked to maybe three people. One of them turned into a genuinely useful conversation about a role opening up. Still don't know if that ratio is normal or if I'm just bad at this. How do introverts here actually approach these things?
