Ask HN: What are the single person activities in Christmas and/or New Year?

In most big cities there will be an underground trance or techno rave that goes on much longer than usual on New Year's Eve. Perhaps try one of those. No-one will care if you are there on your own and you will probably meet some great people.

Go to a nice coffee shop, get a gingerbread latte and sit by a window, watch people walking by and write (or hope a cute guy comes to talk to me ;D)

This is just one small thing, but you could hang out at a music store, and ask questions about instruments. Ask one of the guitar techs to show you how to play the bass, or ask the drummer guys to show you how drums work. Not spend all day there, maybe 30 minutes or an hour, but could learn a lot and might find that you enjoy one of those instruments.
