I was 18, he was 13! Met at his house (I had just started working with his sister). Didn't think much of him then.
Years went by, friend moved to London and I used to go and visit and sometimes met the little brother, who was now 6ft and really nice to talk to.
We started visiting each other more and then married when he was 23 and I was 28.
Marriage a bit of a mess now but it used to be good!
