By “party”, I mean a physical social gathering of people for the purposes of having fun. It may be used in a sentence as “I am throwing a party!” or “Let’s party!”.
Basically what I am trying to say is the default “party”.
I’ve never been to any, and I have no idea how people spend their time on parties, so I am curious how you did.
You can either walk around and talk to people (most people are receptive to being spoken to) or nervously hold your drink in hand, as you wait for someone to approach you.
Personally I prefer the former. If I'm by myself I just look for someone who seems nervous and uncomfortable. I'm friendly, and as long as I'm in a good mood I tend to make people feel comfortable around me- but I have had times where I just stand there. Standing and waiting is highly unpleasant. Better to hide in the bathroom if that's what you'll be doing instead of chatting. Highly recommend chatting or "mingling"
(If someone is lame, boring or seems uninterested, just approach someone else. Most groups will also make a space for you if you approach them in the event that there are no loners)
This part is hard but you need to push yourself through it. The worst thing that can happen is that no conversation develops and you have to do it again.
Another favorite of mine is walking around to see what different groups are talking about. If there’s a topic that you know about, just ask them if that’s indeed the topic of the conversation and if it is, you just joined.
