ponygirl you are contradicting yourself left right and centre.
YOU find this man creepy - therefore maybe someone else could find YOU creepy
YOU dont want this man to assist with swimming - therefore maybe someone else doesn't want YOU assisting with the swimming (maybe that's why you only got one session out of seven?)
YOU haven't been CRB checked so YOU could be an abuser.
YOU say "I volunteered to keep an eye on my kids not to abuse others" - maybe this man volunteered to keep an eye on his kids not to abuse others.
This is why people are starting to get wound up by you - listen to yourself and see how paranoid you sound when you look at both sides.
Can you really not see what you are doing to your kids here - can you imagine how messed up they are going to be if they grow up being scared of everyone and everything.
I am a WOHM, DH is a SAHD. Next year DD will start swimming with the school and no doubt DH will happily volunteer to help out. He has already accompanied the children on 2 museum trips and has given talks on both his previous career and 'what it means to be a dad' to DD's reception class and the Year 6's.
He would be devastated if he thought anyone was thinking this of him, why would you do this to anyone "a bad feeling" FFS - what a stupid reason.
