That's a REALLY good question. Almost everything I love to do requires natural light: photoshoots, recording for youtube, drawing, going out for a walk, go shopping... so there are a very few things I can do when it rains.
1) Workout at home:
It's useful for sure, but I "only" workout for 1-2 daily hours, so I'd have to think about something else to do for the rest of the day.
2) Watch shows or movies:
This is the most frequent option. I'm a huge cinephile and I'm usually looking for new shows to watch, so it's a good chance when it rains and I can't go out to enjoy some.
3) Draw:
I prefer to draw with natural light because it's better to see the real colors I'm using, but with a good lamp that's no big deal, and it helps feeling time is passing faster.
4) Sex:
Heh. I don't think I need a description here.
5) Play videogames:
Also a great option, specially when you just got a new game to explore and you can forget about the world out there.
6) EAT. EAT A LOT:
Highly recommended if you combine it with number 2). Because everybody knows rain is a perfectly valid reason to eat with no fucking control.
