Oh man... so many things...
Negotiating - She can get you to pay her for the privilege of doing work. She's just ridiculous. It's to the point where I didn't even go with her to buy our last car as I honestly believe that I would have cost us money.
Organization - She's the most organized person I know. Everything has a place.
Preparation - It doesn't matter what it is. If I need something completely random for a job or activity, I just ask her where it's at. Not, do we have it, but where it's at. Because I know she planned ahead.
Budgeting - I'm terribad with money. If it was up to me, we'd live like kings until the few days before we got paid where we would be living off of hotdogs and fighting the dogs for table scraps.
Education - My kid is top in his class in both reading and math. 100% her. She's got a masters in special education and has worked in both math and literacy intervention for over a decade which has really helped her break education down to the smallest pieces and customize learning plans. She's taken that knowledge and used it to make my kid look super smart even though he's got 1/2 of my (allegedly) brain.
Video games - I've been playing video games for 31 years and am able to master most games fairly quickly. She masters them just as fast but always seems to be 10% better than me. Her twitch reflexes are just crazy good.
I am better than her at pool though! Although, she's definitely in the top 3 or 4% in that category.
