I like to sometimes stay up really late to work on something that's for fun. Something about being the only one awake, sipping coffee in the glow of my laptop screen.
Same. I have a few 'pet' projects of sorts that aren't really going anywhere, or worth anything, but I do my best to still work on them in the evenings or over the weekends. People think it's weird that I relax from my full time job as a programmer by writing more code.
