Firstly congratulations on the legs. You never know when they might come in handy.
How did your coworkers not notice. I call it look without seeing its how you can walk past some people without realizing their there. I've found unless you work in an occupation where you have to be alert to people and your surroundings constantly (security, law enforcement, medical, hospitality-under age drinking) people tend to look and then dissappear into their own world. Sad for society but good when you want to slowly come out.
