Today I took my son to see his grandad that I'm not related to and he had a lovely time like usual. My son doesn't have a father but I've always reach out and kept his grandad/greatnan/uncle etc an important part of his life. I honestly never thought about not doing it but I realise I don't know anyone or have met anyone who says they know someone in a similar situation. But I don't believe for a second that I'm the only one. Right?
