How crap are my observational skills?
To be fair, two of them are in a class I only teach once a week and I didn't do the seating plan so I didn't notice the surnames.
But seriously, that's rubbish!
(Not going to do anything about it or anything. I'm not going to start saying 'ooooh you're a triplet!!' I just thought it was funny I hadn't realised by looking. The other teacher said something about 'the triplets' and I said 'who are they then?' and she said 'well you teach all of them!' )
