It hasn't upset me.
Not much does.
I'm of the opinion it's better to talk, than bottle things up, and let them fester.
Okay, gladly no regrets, but I do look back at some of the daft things I've done, and laugh.
Like thinking I looked 'cooler' never smiling. When in reality I just looked like a miserable git.
Some of the things I used to wear make me chuckle now. Think of the weirdest punk, or New Romantic, and times it by ten. If you're going to be outrageous, be the most outrageous, and I was. Strangely I never pulled much in those days.
