You know how usually at parents evening the kids' trays are out on the tables for you to have look through whilst waiting for your appointment with the teacher? Well I'd always naively assumed that you were only supposed to look through the tray of your own child. A friend of mine mentioned that she looks through the work (exercise books etc) of children other than her own in order to compare. Tbh I was really shocked - is it me? Does everyone else actually do this & I didn't realise? She (and others I've talked to) didn't think it was any different to work being on the wall. Is it?
