I don't remember teasing Sister when we were kids. Perhaps it's because our age gap is so great, ten years. Little Jo is her mother reincarnated and while I do try not to do it too much, I do tease her. Actually at times I do tease Sister now, and like her daughter, she always bites.
The thing is that Little Jo is so pedantic, and while she is incredibly smart, she doesn't get humour terribly well.
Maybe it is more a dad joke problem.
I did once make her laugh when I sang Humpty Dumpty and slowly pushed an Easter Egg off the bench when Humpty had a big fall. Of course the egg smashed within the foil. Sister said, see Andrew can be funny at times.
Little Jo, did you see Nanny in Packing Ham.
Andrew, Nanny lives in Pakenham.
There used to be a factory there where ham was packed. Isn't it called Packing Ham?
This is a post going nowhere because Little Jo immediately tuned back the 'screen' and ignored her silly old uncle.
It is interesting to note though, while she is completely tuned out to conversation when she is absorbed by screens, she does hear anything relevant to herself.
