Well, it takes time. You gotta let them get used to you being there and at the same time have them act normal and not pose. Cause the idea is to capture the truthfulness of the moment. After a while you become invisible and it's magical because they allow you to be part of their lives for a while. I think it's one of the hardest things to achieve in documentary photography. You gotta have their permission and complicity to get it done right, and at the same time become invisible to them. I've been kicked out of many houses too. haha
