My grandad on my moms side was a bit of a card, sadly he is no longer with us, but something I will always remember about him was his tales from WWII, from as long ago as I can remember he used to tell me stories of being in the RAF, how he preferred the Hurricane to the 'pretty boy' Spitfire, how the plane got him home when it was shot to bits, tales of coming out of the sun and watching Jerry erupt in a ball of flame after a quick burst from his guns and many other stories of flying fighters during the war.
However, at 16 I discovered that although he was in the RAF for the whole of WWII the nearest he came to fighting was boxing for them against the other services. He was a lorry driver before, during and after the war.
So what porkies have you been told that you still remember fondly and deep inside wish they were actually true, but do not feel any resent/animosity or whatever that they were not?
