How do you always win at Jenga? You play against people from the Parkinson's disease center.
Why would you make that kind of joke?
I'm just saying that they're really bad at Jenga.
I think making fun of someone with Parkinson's because they have trouble controlling their hands is a really cruel thing to do. I'm sure people who have this issue are self-conscious already, so teasing them about it probably won't help. I think it would be good to put yourself in their shoes for a moment, so you can try to understand what they're going through.
