My knack would be empathy. It’s already strong enough that I get headaches in large groups of people, especially if those people are particularly miserable (retail, shopping, sometimes movie theaters or family gatherings. UGH the family gatherings), while if I’m in a large crowd like a convention, where it’s all high energy and excitement, I actually get energized by it, though later on I crash and burn and spend the rest of the day listless. I think I’d have a strong enough empathy to know just how someone else is feeling, and possibly help reflect my own emotions back at them if they need a boost.
What would your knack be? Let us know!
