how do deal with this one

[AnotherParadox]

Deliberately keeping this vague but how do you deal with the boy who has bullied your son, teases him on a daily basis, trips him up and on one occasion pushed him up against the wall in the toilets ...... this is in small spats over a couple of years so since y5 - suddenly focussing on your son to become best buddies and invite him for playdates and sleepovers.

Out of interest wwyd?

Personally I would keep my distance. I'm not saying a leopard never changes his spots, but I would be very cautious about a sudden change of heart.

I would talk to his parents about his behavior. I think it is the best thing you can do as of the moment.
