I listen before I talk... which means that when in groups, I almost never talk at all. If somebody stops to ask me, I occasionally get that sort of "Wha? OH. Hmm." look, which is fun.
Also, I parent my two teenage daughters. Pulling the social one back home to do her homework and pushing the anti-social one out of her den in the basement to get some sunlight... I could do it all day, which is just as well.
It might be more fun to wonder what I'm *bad* at. I completely can't play any instruments, am sort of okay at painting and drawing. I'm utterly inadequate at long walks (broken ankles, woo!). Don't ask me to navigate bureaucracy. I go completely deer-in-the-headlights at door-to-door sales people, though I do manage to throw them out without buying anything.
The last musical thing that really struck me was running into ThePianoGuys' version of the "Mission Impossible" theme, which trailed off into looking at random Lindsey Stirling videos at three in the morning. In the background, I keep listening to Foo Fighters, Amanda Palmer, and various really skilled guitarists.
You're okay with being messaged now and then with "OMG look at this cool thing about proteasomes!," or maybe "Linear B!" or "absorption spectra!" The thing with the proteasomes really was pretty cool.
