What is your worst talent?
Or it could be phrased as: what are you really bad at? But I phrased it as 'your worst talent' because sometimes you might be good at something that might not be something good to be good at.
I'm really bad at dialing phone numbers on a regular phone. Cell phones aren't so difficult but I think I'm button number challenged. I'm also pretty good at riding my bike with no hands.
Yes, the photo is me, with a beard, wearing my favorite hat that I lost. I should mention that this photo was taken in Greenland.
