Do you need the concept of sampling explaining to you?
No, but again, it's a small number and just a sample.
Do you want someone to explain the difference between a school uniform and wearing a mask during a global pandemic?
Again, no. Uniforms are absolutely pointless, and as far as I'm concerned masks on kids are almost just as pointless. They won't be changed regularly, they will have to be removed for certain activities, kids will fiddle with them constantly having them on for 6 hours a day. Christ, adults can't be trusted to wear them properly not much chance of kids doing it. Pointless.
