Ok, so I wasn't the sole host or anything, but my housemates and I threw a small party and I made the last minute decision to actually invite people. About 5 of my friends did show up, which for me is quite a success! It was a Halloween party; I dressed up as Newt Scamander, made sangria and a "graveyard cake" with a barbie arm sticking out of it, and introduced my friends to a fun drinking game (and some bananagrams). Surprisingly I had a really great time, and I think most of the guests did too. I used to kinda hate party games, but now I appreciate them - if you choose the right ones, it's a great way to get everyone involved and feeling included, and doesn't put a huge burden on guests (or hosts!) to initiate conversations with randos all night.
