My husband shares my enthusiasm for cleaning/repairing the vintage machines - and has been known to buy them himself. We both share a gardening hobby/passion and spent the last two days getting the greenhouse ready, tilling the new vegetable garden, and working in some of the flower gardens. He does not share in my quilting hobby and so far I don't share in his model train hobby (although when he gets to the design stage he wants me to do some of the detail painting because I can).
I love it that we have "my" and "our" hobbies. I think it's important that we both have some "me" time and some "us" time.
