I have an eight year old daughter. I don't like one of her friends' dads. I have absolutely no reason for disliking him except that he gives me the creeps. I don't know why, and there is no specific evidence that I can pinpoint at all in the slightest. My daughter has been in his care once. The mum arranged a playdate and didn't tell me it would be the dad looking after them so I was slightly taken aback and checked in with my daughter that all had been ok with this man (a stranger to her) and I'm confident that all was fine. So I genuinely have no reason but my gut instinct tells me to keep my daughter away from him, to the extent that I am slightly standing in the way of her friendship with his daughter by refusing invites in case the dad is there and not the mum again.
What do you think - trust your gut or tell your gut to stop being stupid, you have no evidence and you can't go around judging people just because something about their manner makes you feel uncomfortable, but you can't pinpoint what?
