Seeing friends or family face to face.
And the idea of just being able to go into any store any time without much thought. Now I technically could do that anyway because lot of stuff is still open, but I'm being responsible and avoid store visits unless absolutely necessary. Some stores are also order/curbside pickup only such as hardware stores, so even if I want to cheat and I need something quick, it's not that easy now, have to order and wait. Generally though I'm seeing that as a minor inconvenience that I'm willing to live with until this is over.
At this point I'm not letting too much of it get to me, I'm just glad I still have a job. I could be in a much worse situation such as being laid off and wondering how I will pay all my bills, including anything that may be deferred. It still needs to get paid at some point.
On my days off I'm basically doing the same things I'd normally be doing like working on house projects and stuff.
