I had a few hobbies I did on my own that my FH has picked up to do with me, and vice versa. I've been doing obstacle course races/mud runs for 4 years and my FH decided to do them with me starting this year. We travel around the country doing them. It certainly makes me a lot happier to have someone to talk to out there as I trudge along. We also travel around to various vineyards together. I'm *trying* to pick up more outdoorsy habits since that was one of his things, but it's a trying process.
What have you picked up from your soon-to-be spouse, vice versa, and what have you picked up together?
