I picked "everywhere", but with some caveats:
1) I wear a diaper to bed every night and sleep-wet sometimes.
2) I don't tend to wear them around the apartment unless I've just woken up, or just returned from running errands and am not soaked enough to change out of it. The toilet is just 15 steps away, and I'd rather save my diapers for when they can be most useful.
3) I nearly always wear diapers (sometimes pullups) when I go out, including get-togethers with friends and family.
4) I don't generally wear diapers to work, but have worn pullups sometimes. I've been unable (just subconsciously?) to actually wet myself at work, and if I switched to diapers and somebody found out, that would force me into a long-term commitment.
5) I'm long out of school, but if I ever took some classes, would definitely go diapered! (But I have a very hard time peeing while sitting .)
