Reading a book to my son this evening and there was a picture of a wicked witch. He said instantly that looks like aunty X (sil). I thought this was odd as even though a cartoon picture if bore little resemblance so I asked why and he replied 'because she looks nasty and shouty, and Aunty X always shouts and is horrible to me'. I asked him to expand and he just kept saying she does horrible things. He does spend a reasonable amount of time with sil and though I've never seen this I'm concerned. DS is only 3.
