BS (Before Salsa): I mostly stayed in the same social circles – my friends that I’ve known for years and their friends plus friends from work. The problem is that these social circles are mostly limited. New people rarely enter into these social circles.
With salsa, I am able to expand that social network to lots of new people. And even though I think I have more friends who have quit salsa than have continued, I will still keep in touch with them. (I went to Las Vegas for a bachelor party for one of them just this past weekend, in fact.)
Also, it’s much easier for me to make new friends in new cities. BS, my other hobbies aren’t quite as social, and I wouldn’t make as close friends as I do with salsa.
One of my biggest obstacles in having moved 2x in the past 2 years, is starting over socially. With salsa, that transition is much smoother, and it’s not as traumatic leaving all my friends behind.
And finally, with salsa, I have found a way to comfortably flirt with strangers. I won’t continue if it’s not mutual, of course, and I will just dance friendly instead. But it’s nicer than merely trying to chat someone up at a bar.
