tufty, it's very interesting what you say about potential paedophiles trying to blur the physical boundaries over time. I feel that's exactly what the two men I described have done, whether wittingly or not. It left me feeling confused and unsure of my own judgement.
If the men had been related to us, like the male cousins RobinW describe, I would have felt much more OK about their involvement. Even though I know much abuse occurs within families. Mad I know!
The thing is, the family man initiated the rough and tumble - and did so on some other occasions when I was there. If he had been fending off my son it would have been a diferent matter.
Thanks LisaV for finding out that info on sex offenders. Very useful!
Just for the record, I have not banned my son from seeing these men, but I am attempting to remove what I perceive as the risk. My son was given a really useful book by our local police representative, who handed them out at his playclub. It was written for him, not for adults to read, and gave him strong guidelines on how to behave with strange adults or in strange situations ie if lost and there is no policeman around, approach a shopkeeper or a family, not a lone adult. And, if an adult ever touches you in a way that you don't like, do not be afraid to make lots of noise.
As far as I know these rules are not reinforced at school in the same way as the highway code would be. Perhaps that's what needs to happen - a new code for children to make them more aware of what to do when they are with strangers. But then you have the 'taking away their innocence' argument to consider.
