Anything mechanical. When I was going on active duty in the Navy, the CPO administering the test to reveal where I might be a fit, called me into his office and I remember this like yesterday because it's been this way all of my life. He said "you scored in the top 5% except in one area, mechanical/technical". Then he held up a screwdriver and said "what do you think this is and which end would you use"? He busted out laughing and said he'd never seen a score so lopsided and it was obvious I am not a dummy but how have I lived that long?
I am just not good with my hands and I do envy men that can make furniture like my daughter-in-law's Dad, he made the grandchildren some great wooden toys for Christmas and they looked beautiful under the tree while they played with the haul I bought from Amazon.
I jest, and always have about men that are really good around the house, because I really am envious of their ability to not be dependent on service people. However, most of them can't write stupid poetry and I can and life evens out. And I am a better mixologist and I ain't putting a grill together but I can cook on one.
BTW, putting a gas grill together when we moved into the neighborhood in Baton Rouge was how I met the neighbors...….and the fire department.
