It's legit kind-of great, because you can't be doing much productive, so the dozen things you should be doing (most of them due to kids...) if you were at home are out the window. You can just chill for a long stretch of time, without concern. Taking your kids to the park or whatever is awesome, it's one of the best breaks a parent gets during daylight hours.

Or you can knock out some schedule stuff or teacher-emailing or bill-paying or whatever that you'd otherwise have to cram in some other time, that's nice too.
