Inspired by another thread (but not a TAAT).
Is it unreasonable of me to think that being single and childless (or child-free, but particularly childless) is very different to being a single parent? I'm not saying it's necessarily better or worse - I think it's sometimes more lonely, but probably less stressful - although I do get a little cross when people say they live alone when they actually share their home with children who love them. It's also very easy to feel marginalised if you are neither part of a couple, nor a parent.
I'm sure that being a single parent must bring with it a lot of worries and difficulties, but not having a partner or children can feel spectacularly shit sometimes, particularly at this time of year (dark and cold, Christmas, Valentine's Day, Mothers' Day, etc.).
Not particularly trying to argue one way or the other, but would be interested to read people's thoughts.
