So many of these couples have a father older than the mother. My parents met at university, so they were the same age. 18 when they met, 28 when they married.
Dad 1918 and Mum 1922, they both died in the 70's following many years of ill health. I've lived longer than either of them but really never got to know either of them before they died as they were always rather "distant". I have a completely different relationship with my daughter!
