Hiking - sounds attractive, but the woman may not actually enjoy hiking especially doing multiple day trails

Woodworking - “wow you made this desk yourself?!” Reality: Spent weeks designing and getting the right materials, spent more weeks in the shop getting everything right, spent months all together away and in a shop so you could present… a desk (the novelty runs out real quick with a partner)

Same with a lot of them, if you’re really into a hobby and it is presentable… You’ve spent a fuckton of time on it. Something you could do while you were single, 10x harder to pick up or continue doing in a relationship since your time is now divided. It becomes one of those, “Yeah they love doing photography and they’re really good at it!” (cue partner standing there who hasn’t taken a picture in over a year looking sheepish).
