My theatrical activity is usually acting in plays ("playful"), but this season I have been working on the tech side, instead (building). I wonder if that could be the connection.
Also, taking the playful kitten idea more literally, my cat's health has improved lately, and he has become more playful, more like he was when he was a kitten. I have felt guilty about the years when his diabetes and Arthritis got bad and I lived in a slummy area. I have a nicer environment for him now, and have started feeding him a raw diet, and he is very happy now.
