I am 28, hubby is 29 and people look at us like we are from another planet when they find out we have 7, yes 7 gardens, goats, chickens, and ducks. We are the only people we know who raise chickens for eggs. I will never again buy store eggs. We are rasing goats to sell to the 4-H and FFA kids and already have orders for next year and we haven't even had any kids yet!
The stuff I grow in my garden is far superior to anything I have bought in a store. Hubby and I start everything from seed in our bedroom. We have such a great feeling of accomplishment when we harvest and then can or freeeze what we grew. It is so nice to be able to walk outside and pick a tomato, some lettuce, a carrot and go inside and make a salad. This year we added fruit trees to our yard, plus a lemon, lime, and orange tree to our bedroom (don't ask!)
I love the fact that I have to buy very few things at the store and haven't bought store canned veggies in over 3 years!
If your "friends" don't understand what you are doing, then I guess they weren't real good friends to begin with!
