I was on a very busy train with my 6 yr old G/Daughter, in a loud voice she said "Daddy liked the handcuffs Mummy gave him for his Birthday" well everyone in the train carriage stopped talking and looked in my direction, i could feel my face going redder and redder, i said "oh i think you have got the wrong name for them" she said "no Nanny they were handcuffs " i just wanted the ground to swallow me up as this was too much info on what my son and his wife did in their home, G/daughter then said "you know Nanny those handcuff things Daddy puts in the end of his shirts on the cuffs !!!! well with that the people in the carriage started smiling when i said to her "oh you mean cuff links !!!! ,"yes thats what i meant Nanny" !!! when i got off the train a lady stopped me and said" i dont think i will ever forget that conversation , i told her nor would i ,lol.
