I can ride a unicycle and rode it more often as a teenager. Lots of comments about getting lost from the circus. But they were meant to be funny. I think.
My experience is that greatest predictor of what kind of response you get when doing something unusual in public is whether or not the activity is solitary. If you do a solitary activity that takes a lot of practice, it suggests you're some kind of weirdo loner who has to fill the empty days with hobbies because no one wants to hang out with you, and responses in public may reflect that.
If you're doing an activity with someone else, then at least one person doesn't think you're an intolerable weirdo, so people seem to be more accepting of it.
The responses I got between when I was juggling alone versus club passing with another person in a park were very different.
I guess a tandem isn’t as uncommon / funny as a unicycle.
Now I’m curious how the reactions would be for a tandem recumbent tricycle. (Yes, they’re a thing.)
