I generally don't pay much attention to holidays so it doesn't get to me. I usually spend most of my days alone anyway. I'll be listening to audiobooks on historical figures like I usually do. I'm also active in a lot of online communities so there's a good chance that I'll be able to talk to someone online, but it's not as easy as it was back in the day when chatrooms were everywhere and always heavily populated with people to talk to.
It's nice to come across a nice active IRC channel on days like that.
