I remember a couple of years ago a man moved into my street, he kept himself to himself and just smiled at folk, but whenever he saw a dog he made a right fuss of it and asked about the dog, but then the next time, he'd ignore you. I hadn't seen him for a while, but his van was still outside his house and then I met a neighbour who told me he had hung himself. I didn't just feel like sobbing phleb, I did sob long and hard and I barely knew him. What you are feeling is totally natural and shows you care x
