They make the choices that circumstances dictate. Or even, god forbid, don't think about it very much at all.
For example, in my case, working when my babies were small. I didn't think about it and make the best decision that I could, taking into account every aspect of the situation and everyone's opinion. I just assumed that I would go back to work. Never even questioned it. Finances dictated and nothing much else got a look in.
Aren't most people like this? Or do they all buy the equivalent of Which magazine about every decision they make?
