I have noticed that people who are used to wearing slippers or sandals either outside or at home tend to drag their feet. If they don't, the footwear comes off. The foot dragging must be habitual.
I don't think much of people who do drag their feet. In my experience, the people I encounter who drag their feet also drag their brains around with them..
If you drag your feet and are a skater/surfer dood.. then hey it's probably cool. If you are in a technical profession, drag at your own risk - you will be judged whether its fair or not.
Sorry, by referencing myself I should have clarified I meant me and my clones. Sure, you have to anticipate the occasional genetic defect, but they're invariably great banjo players: **broken link removed**
