Funnily enough, OldandProud, the friend whose grandson it was (heās a teen now) also has a nephew who used to come out with the most extraordinary things when he was very small. His parents used to ask him how on earth he knew whatever it was - they couldnāt understand it.
He would just reply, quite unconcerned, āOh, I learnt that when I was here before.ā
But again, after about 5, it all stopped.
Another one - a BiL was married to a Singaporean Chinese and when one of their (now adult) daughters was 3, my dd was staying with them in Singapore and pushing her on a swing.
The child started talking about the house being on fire, and her daddy being very ANGRY!.
Dd was startled and concerned to say the least, since BiL was always so utterly laid back. So she said, āIām sure your daddy would never be angry like that!ā
3 year old said (as if dd should have known!), āNo, not that daddy, I mean my other daddy, before.ā
Singaporean SIL thought nothing unusual in all this, said sheād come out with similar before. But again, nothing after 4 or 5.
Apologies if Iāve posted all this before!
