Whilst having a mosey around a supermarket with my DS [20months] in his trike, chatting about what we could see and what we should buy I notice a boy of about 3 at most 4 but not in school uniform and it would have been the right time for school children looking at DS and following us around. No idea where his parents were as I was mulling over something for a while in this aisle and saw no sign of them. He then went up to DS and pushed his head and chest out [like men do when they're being aggressive and asking for a fight] then he flicked his hand up very quickly, not sure if it was the right finger but the intention was definitely there, I then asked him what he was doing and he ran round the corner, but still kept looking back round at DS. I was so cross I didn't know what to do, thought I should find his parents and tell them... but when I went and saw his Dad, I realised that he was a traveller and therefore may not necessarily be bothered by this behaviour, as it is often their culture for children to copy adult behaviours plus I did not want to go and approach him when I was on my own. My DS bless him, just looked at this older boy quite innocently and then a bit confused as he was acting so strangely towards him, it was me who felt like steam was coming out of my ears I was that bloody angry!!!
