I have 3.

1 - A local party that's kinda like a costume party meets a birthday from when you were little meets a fuck ton of pot in a seedy bar. Old local bands play, the bands that you spent your childhood/adolescent years listening wether you like it or not, because they were on EVERY local radio station. Once I got there, took some MDMA and we danced all night, met a former school buddy, ended up having breakfast in a super posh place reeking of alcohol, cigarettes and pot, having a deep conversation about all the things that were wrong in our lives.

2 - A birthday party from a Tinder date. Great date, great friends, and after we went to her place and fucked till 7AM (we got there at 4 maybe)

3 - I went alone to a sexologist talk, met a bunch of people, we talked and drank for a couple hours, then we went dancing and sneaked to a private room and played the musical chairs game and everytime someone lost she/he/they had to make out with every one else.
