I guess that, if you don't mind people staring, you can do Tai Chi anywhere. Even in the middle of a busy airport hallway. He wasn't the most graceful Tai Chi practitioner - in fact, he looked more like he was trying to dance to some bad disco music - but neither that nor the hordes of people walking by stopped him from doing it. As strange as it seemed, I admired him for doing it. I mean, there have been times when I've wanted to the hustle or the funky chicked in the middle of a public place but haven't had the courage to do it.
I might someday, but something I know I'll never have the courage to dress up in a fuzzy pink sweater and dress my chihuahua in a matching outfit.
But I would wear the backpack with the big rubber tyranosaurus rex head stuck to the back. That was just cool.
