" Opa and Oma, their children and grandchildren, celebrating someone’s birthday or an anniversary. They tend to sit there looking a bit lost, waiting for one of the children or grandkids to make an attempt to draw them into the conversation. A conversation they have trouble following because of the ambient noise, and anyway, what the others are talking about is often way over their heads. They’re sitting there, but they don’t really belong, not really. "
