One of the many things that seems at the moment like a distant memory is - parties. Personally I don't see this as a loss, as, with very few exceptions, I hate parties - but I think they might be quite fertile ground for writing. Here are some suggestions:
Write a shortish piece about a party when you were a child, a teenager, and an adult.
Write a longer piece about a party you particularly remember - whether because it was great, or because it was horrible.
Write a story centring on a party. There are lots of parties in films, aren't there? I guess because of the potential for comedy/disaster/arguments/new-found friendships etc.
As ever, strongly suggest starting with a spider chart and jotting down lots of details - the food, the clothes, the setting, the way you/the narrator feels...
Goodness, it gives me the shivers just thinking about it.
