On a simple level.
One does something comestic to enhance one's appearance.
Like many people who were bothered about physical appearances would if they were going to somewhere where they would on display . A wedding or a Christmas Event or who knows, the school run.
Then, an opportunity comes up where you are going to be on massive public display.
Is it so very unreasonable of me to think that if you were the ilk of person described anove, it is strange not to get yourself up to your normal appearance?
