To cut a long story short I had a nightmare experience with a boy DS2 had home for tea a couple of months back - it was a "return the favour" job and by the time he went home I thought "vile child and horrifically, rude mother". Anyway, DH and I were away for the weekend and a friend of mine was looking after the children. While waiting to collect DS2 from school this kid's mum came up and basically tried to bully my friend into taking this child home to our house for tea, despite the fact that she had never seen my friend before in her life. The mother turned around to my DS and said "you want X to come back to play, don't you?" at which point DS2 replied "I don't think my mum would like that. The last time he came she said he was really rude and bad mannered and it took ages to get rid of him when it was time to go home". Oops
