I've changed my name for this as I don't want to be found out IRL.
My child A has just gone into Year 2 and has become very friendly with child B. There have been several playdates at each other's houses and they play a lot together in school.
Neither of B's parents work, and whenever I go over to B's house, the dad is always on his way out or out somewhere. The few times I have met him, I have had suspicions that he is mentally ill (I have some experience in mental illness). I am not saying this as a bad thing, and on its own I would have no problems.
However, I have recently heard from a reliable source that the dad is permanently stoned, and is often to be seen smoking joints in the street or out of the window.
I do not feel that this is a good environment for my child to spend time in (goodness knows, I am no saint, but I think this is going too far). Dh thinks I am overreacting but I am very keen to encourage my child to find other children to play with. I know that I don't have much influence within school time, but certainly I will try and arrange play daters with different children.
So, am I being unreasonable?
