My office window looks out onto the ramp that leads to the accessible entrance of our building (the ground floor is set lower than the street and the grass outside, so there are four or five steps down to the door, or a long zig-zagging ramp). When I got back from lunch today, feeling tired and slightly grumpy because I'd had to go into town, which was Too Peopley (it's always Too Peopley, but clearly COVID makes that worse) and with an afternoon of meetings ahead of me, I discovered three small children using the ramp to rollerskate, and, being tired and grumpy, went out to grump that it wasn't a skate park, and people were trying to work in the building. At which the woman who was with them was so apologetic I felt a bit bad for being grumpy (though I still felt it was a reasonable grump).

Of course, it later turned out that they were the children of the new warden of the college accommodation over the road, who came over later on to introduce himself and apologise again, and followed it up with an email. So now I feel rather embarrassed for making a fuss, when it probably wasn't that big a deal anyway, and if I hadn't been feeling tired and grumpy to start with I might have just let it go with a bit of tutting...
