I found it interesting that one poster thought that having untidy hair meant a person was disrespectful to the audiences/people in general.

When people's hair is untidy, it has nothing whatever to do with you, and has a lot to do with them.
1. Were they depressed or ill this morning?
2. Do they have fine hair that no matter how much gel and spray they put on it, a gust of wind turns it into a haystack?
3. Do they run their hands through their hair when they feel confused or upset?
4. How many cowlicks do they have? (My dad had 6 and it was very difficult to get his hair tidy. The only solution was to part it dead down the center, so he always looked like the 1930's as to hair).

and so on.
