When my GSwas about 5yrs old he was reprimanded for saying "Oh God!"
His reply was, "I musn't say "bloody hell either!"
We were at a Carol Concert where Choir and audience were singing, "The Virgin Mary had a Baby Boy", when my nine yr. old GDD pulled my sleeve asked,"Grand-dad, What's a Virgin?". Hurried confusion on my part: Well dear , it's er, a lady who has not got a husband". GDD. "Oh, what about the baby?" Me. "Well, do you remember the Archangel Gabriel came down to see Mary?" GDD, Oh - It was him, was it!"
That was many years ago now and GDD, now 17 does not like being reminded of it!
