When I first started gardening, I had a few friends and family that thought it was strange that I would put so much time and energy into growing vegetables, when I could go to the store. But on the flip slide, I had friends and family members that absolutely thought it was a cool and powerful move. Many of my naysayers have actually started vegetable gardens to help with their food budget, and guess who they called when they wanted to get started....yeah, me. So, keep doing what you're doing because like you said, "they don't know what they're missing."
