Last week I went on a weekend away in Italy with dd who is 2. We were in a city in a quietish area and a man who looked in his fifties wandered over as I was walking with dd and looking at my map (so I was slightly preoccupied).
He stroked the top of her head and probably did a couple of strokes with a strange look on his face when I pulled dd away and said sternly to him 'no, sorry' so that he would back off. He wandered off and didn't say anything, so I don't know what he was thinking.
I am still alarmed by it, I feel that walking up to a lone mother and her child and stroking the child's head is really wrong, he never said a word or started a conversation with me, his behaviour really awoke the lioness in me! If it had been UK I'd have been absolutely furious, but I know Italians are more tactile in general.
