Exactly, they could post a nice pic of the setup an caption it with whatever it is, like here's our mother's day event where mothers will enjoy such an such an the kids will do such an such, or today was such a great day where the kids done such an such for the mothers etc, no one needs to be in it,I don't see why they don't just post photos of the events and maybe the teacher etc. There is no reason that they need to post the kids.
Makes me wonder if even the teachers are happy about it as well an even have a choice if they want photos, I know I'd be pissed, am doing modules at work for qualifications an one of them am supposed to be observed but they can't be bothered coming in so want the photos for the "proof" an I've already made it clear how fking angry I am an have told them fine but I'll have a face mask on an they can take it or shove it
