Hmmm yes you've rumbled me girls. The man is indeed only 50 and not really old enough to be my father! He was 9 years younger than my mum when they married and he took my sister and I on. He seemed very much older than his years though, he is an old soul, and was very sensible and strict too!!! Everywhere I went women used to comment on how gorgeous he was, (the dental nurses always flirted with him), and as I got older they used to ask 'Is that your boyfriend?' 'Eeeeeuw no way' I would say, 'He's my dad, he's gross!!" I couldn't see what the fuss was about!
I was too old to call him Daddy and he was too young to be called Dad so we called him Pops as a bit of a joke! He now has 2 of his own children with his gorgeous American born Japanese wife, they are the cutest looking things, but he still considers my sister and I to be an important part of his life.
I couldn't possibly do a family tree or even try to explain my family situation, I simply haven't got the time. It's complicated, and has many branches. More like a family forest, hehehe. Let's leave it at that!
