Improvisers say "yes", obviously.
Not just on stage. But everywhere. All of our training has led us to subconsciously become more agreeable people. Certainly, I find that's the case for myself.
My music has often kept me at home or made me rush back home from whichever event at whatever place. Whether related to the business side or the creative side of things, I've always got a pretty good excuse to get back home and back to work.
I remember one time I was getting picked up by friends at 7pm. Stupidly, as if I didn't even know myself, I picked up a guitar at 6:50 and in that ten minutes came up with a melody I really liked. The result of this? I spent the entire night humming it to myself so that I wouldn't forget it. This was before I had a simple voice memo function on my phone. Fair to say, I was probably horrible company that night.
Since sinking my teeth into improv, I actually feel more free to chase whimsies and live in the present, like improv is the best life coach on the planet. I'm not talking about anything crazy or out of the ordinary, but instead about very simple things. For example, yesterday I had an improv session with some of the guys I do "The Movie" format with and we finished at 2pm. "Old me" thought he was going to grab lunch and rush home to get some work (or, let's face it, procrastination) done. We said goodbye to each other before Tim asked "What are you doing, Broni?" I replied that I was getting lunch and a coffee and going home. He asked "anyone else want to do that?", and "YES! YES! YES!" we all said. We continued to laugh all afternoon. If you're thinking "So what, I'm already a social butterfly and this happens all the time!" then shoosh your mouth because I usually forget to be in the moment, unless that moment is after a four-count from a drummer.
