Easy and rewarding. They see the "goodies" that I share with them as well as my readers, but they don't see the hard work that I put into my blog. (My husband does though!)
My husband understands it as the creative outlet it is, but because he's not a blog reader himself...I don't think he "gets" it as much as he could. He is still super supportive of my blogging, reads my blog, etc.
I recently had my aunt in town and she and my mother spent a solid hour asking the "but what is the POINT?" "why does anyone CARE?" "why do you put it out there for everyone to SEE?" questions. Oy!
