My mum had a scenario recently she has lost some weight, went on holiday and suddenly realised she had lost one of her rings they searched the hotel bedroom etc. she was quite upset. Then later in the day she was rooting in her handbag and there was the ring! it must have slipped off whilst messing in her handbag earlier.
I think like the other OP it sounds like you may have put the away somewhere with all 3 of them missing...I hope you come across them.
What were the first ever records that you bought and when?
Parents-in-Law. What do/did you call them?
