I don't think that's true at all. Children are just as fastidious as the old, they simply fuss about different things.
They want a certain brand of trainers, or there's half a dozen foods they refuse to eat, or they hate certain colours, or their hair has got to be just so. Children can be so fussy over so many things that their parents despair.
In fact I have the impression kids are getting more fastidious by the day. They seem even more demanding and even keener to keep up with what their friends are doing and wearing and enthusing about. Or is that a mistaken impression?
Certainly when I was a kid I don't remember being especially demanding about anything at all. Most of the time I just did what my parents expected me to do. I ate what was put in front of me and I wore what my mother bought for me and I was polite and adaptable. My docility seems a bit pathetic by today's standards but I didn't find it abnormal at the time.
My personal fastidiousness is mainly centred on cleanliness and tidiness. I couldn't stand a house that was filthy dirty or full of clutter. Luckily Jenny is the same. A girlfriend and I once shared a flat with people who seemed oblivious to the increasing grubbiness and disorder and did nothing about it. After several exasperating weeks, we moved out.
Of course nobody likes to be described as fastidious. No, no, we just have our standards and we stick to them.
