I feel for you, Still, and I share your conclusions.

Seeing the picture only makes me feel uncomfortable - like there must be something else going on. There is no way I would ever have gotten (or will get) that close to any member of my own family. Neither of my parents ever laughed like those people are, their smiles were always bitter or angry.

Like Magellan, in my case my partner's family have opened their arms to me and have allowed me to experience what life should be like.
