not sure if this is the right place to post, but need some advice/reassurance. went to good friends party recently, lots of young families there. dh mingling, i was watching dd4 and ds2 playing in garden. was sitting away from them (on my own!) but keep steady eye and just chilling a bit. looked back and saw dd being encouraged to walk up a mans body, eventually resulting in legs on his shoulders....this freaked me out. i acted calmly, walked over and made an excuse about getting more cake! - he however, sought me out a few minutes later to apologise if he had offended me. was i right to be so suspicious? would your partners interact physically with children unknown to them?
