I am a Nana to 4 grandchildren, 3 girls one boy ,eldest is 12 and youngest 6 ( She is the one who informed that all sixes get bored easy, and did I not know this)  My granson when asked to draw the nativity when he was younger drew Mary with what appeared to 2 sticks in her hands, when the teacher asked what they were he said well if she is having a baby she will be knitting baby clothes, that's what my Nana does.
So you can see they have all inherted my sense of  humour and logical thinking.
