No you shouldn't judge on a name, but some names seem to go with certain behaviour.
It can be quite difficult for teachers to name their own children because it is difficult to disassociate the name from a child you have taught.
IME Jess is a bit of a handfull, Jessica or Jessie, fine, but Jess - nope.
All muslim girls whose names start with 'S' are IME lovely. Bright, polite, considerate.
This is probably due to a group I taught where there were 6 muslim girls, all starting with an 'S', some with very similar names.
The worst thing they ever did was swap headscarves at break to confuse me.
AAron is another lively character, OK on his own but group work brings out the worst, and I would never pair him with Liam.
