I did for years. As a child I used to be taken on outings to see Father Christmas, zoos, shopping with a very nice blonde lady. I would have been about 3.
Over the years I would ask my parents who this lady was. She had been kind and I still had a Wade ornament she'd given me. She just disappeared from my life but I never forgot her. Much to my parent's dismay I expect.
So until I was about 60 I would occasionally try to jog my parent's memory about her. She'd been a memory I had never forgotten. My parents would just look at me and shrug, saying they had no idea what I was talking about.
I was sat with my gorgeous Mum one day and she told me who she'd been. Mum was about 86 at this time and had decided to tell me what had happened
Apparently my father had had an affair. Blonde lady had been his mistress and for some reason they thought I was too young to remember so she'd take me out.
So yes, inadvertently putting my feet in it for decades!
