Just a pondering. Mine are OK but I am very different to my brother. I love him and his wife and kids but they are very, very different to us. For example they don't own a single book and treat us suspiciously because we have lots. My Ma is great, none better, but my Step Dad is hard work. My stepsiblings are arseholes, the pair of them so don't have much to do with them.
I have two sets of friends who are off on jolly holidays with their parents this weekend. Dont get me wrong I love my Ma and step Dad and Mum in Law but going on holiday with them is a stretch too far!
