Definitely travel for me. Usually crossing the border at least once a month, I'm just sick of the same environment, same foods, same types of people, all the time. I miss just unashamedly gawking at beautiful ludicrously priced things since we're too protestant to have those. No lockdown necessary for that, it's a family trait and sitting put in one place for too long makes for very restless people (not all of us, but it's a theme).
I miss my Pilates reformer classes, contemplating just buying one but it's kind of an investment and means I wouldn't be going back when they're open normally which feels kind of shitty.
Not missing, social obligations 
Oh and definitely wasn't missing the tourists, it was bliss until about end of May when the Germans started showing up and approaching all Dutch women and insuating we're all prostitutes again (this used to be just the Brits, well, English really) but the current crop of tourists are particularly annoying, drunk or otherwise out of their mind and not giving a crap about any guidelines
