Am I Growing Up?

Growing up I was a blue jean, t-shirt and tennis shoe guy. I would do anything to avoid getting dressed up. In the last month I have gotten the urge to dress nicely. While in Las Vegas I went and saw The Rat Pack and wanted to wear my suit, black shirt and black tie. I felt great being a sharp dressed man. I still wear jeans, but now it's black socks and Doc Martins with a nice shirt. I feel good getting dressed. Help! Does this mean I am growing up?
