My closest friends are from school. One of those friends I also went to uni with and there are a couple of more friends I met in uni. I have been in the same work place for 17 years and have developed some close friendships there over time. I have also become friends with some of DH's friends in the 15 years we have been together. There are also some school mum friends, most of whom I have known for several years as our kids went to the same daycare.
