About my "free food"

Someone commented on my previous entry that food from the garden isn't really free, because my labor counts for something.  
If I considered it labor, indeed it would.  
This reminds me of a conversation I had with a couple of Cliff's cousins a couple of weeks ago.  These ladies have friended me on Facebook, and have found my blog.  They told me they were amazed at all the hard work I do, milking a cow and churning butter and making cottage cheese.  
"That's not work," I told them.  "I'm playing!" 
It's hard to explain to people that I do all that kind of stuff for fun.  I don't have to do it; I do it because I like to, because I want to.   
Financially, we could do without a garden; in fact, I had not gardened for a long time because I got tired of blight taking my tomato crop and squash bugs killing my vines.  Then two years ago, I got a hankering to have a go at it again.  
Last year I had a blast, and this year I've had even more fun with it.  As much as I love the food, though, if it weren't fun, I wouldn't be doing it.  
It's the same with with milking and churning and making cheese.  
I do all these things happily, while ignoring mundane chores like washing windows, cleaning my mini-blinds (I still haven't figured out how to get them down), or shampooing the carpets.  
So:  I have a hobby, gardening.  If I happen to get some food from it, it's simply a by-product, and it's free.  I have another hobby, taking care of my pet cow and milking her occasionally.  If I happen to get some milk or cream or butter out of the deal, that's just icing on the cake.  
Anyone who knows me will tell you that I do very few things that I don't want to do.   
There aren't a lot of people who can say that.
