I had coworkers who worked east coast hours but lived on the west coast, so they were off at 2 every day. A lot of them initially had all kinds of plans for what they would do with their free afternoons, but in the end, seemingly all of them did about what those of us who work til 5 do after work, just with an earlier bedtime.

I worked with the reverse! Boss was on the west coast and I on the east. Honestly much preferred it. Having the open morning and starting work after a no-rush breakfast, some exercise, etc. was divine.
