Ok, I might as well go first: I wish I could draw. Not at the level where I could make photorealistic portraits, but I’ve always been envious of those who are able to scetch something together in a few minutes that perfectly captures what they want to convey. Sometimes words aren’t enough to express what I want to say, and for those situations I would love to have a simple drawing do the talking for me.
My wife can read a a cookbook (or a recipe in general) and instantly contextualize what she’s reading. If I could do that, too, there’d be a lot less strain in our marriage.
For that matter, remembering a list of more than three things for more than twenty minutes, that’s abother one.
