Hmmmm..... I have so many of the same likes as all of you! I would add ice cream to the list as well as books!
Quilters unite! I had a friend once comment on my hobby of quilting, "At least your hobby isn't expensive," (something like that). I was dumbfounded. Fabric is expensive.
I have a part-time job just to pay for my quilting! OK, I only get $10/hr, and it's real sporadic...only about four or five hours a month, but it's something! It means I can sometimes buy fabric, etc., without justifying the expense!
