my father walked away when i was 3/4, it was not till i was 11 (i stayed with my gran a lot) that i started to ask my gran why she was my gran if she was not my mums mum or my dads mum, she than told me my uncle billy whom i had seen a few times was my dad, he came back when i was 17 for my grans funeral, he did not want to keep in touch but i contacted him when my own son was 5, he still said no even though he had another daughter same age as my son. i left it alone for years but started to look at my mum and thought i want to find him before it's too late, he is 75, i posted a message on missing people on facebook, his daughter saw it and my dads stepson emailed with a phone number, i called and the first thing he said was i have been trying to find you for years, we have met up over the last few years and we get on great, i have no animosity towards him, i told him he was the one that lost out on a great daughter and an amazing grandson and now a great-grandson, he is a sad lonely man in his late 70s and has been on his own since his divorce 20 years ago. depending on the ages of your grandchildren tell them the truth x
Parents-in-Law. What do/did you call them?
