When I think of Zork, I think of the Great Underground Empire (before your time, sonny), the Flatheads, and the granola mines. Also, grues. http://en.wikipedia.org/wiki/Zork
I have decided that I won't allow society to tell me whether or not I can enjoy something, based on my age. I have a couple of coloring books (one with geometric designs, the other with butterflies) and sometimes I pull them out and work on a picture or two. My husband got rather jealous of this, so I got HIM a couple of coloring books, too, of muscle cars and pirates. We share my box of 96 crayons. One of the best things about being an adult is that you can go ahead and purchase that huge box of crayons that you always wanted as a kid. A few years ago I bought myself some sea monkeys, which I had always wanted as a child, and which my parents always refused to get me. They were fun for a while, but not nearly as fun as I had imagined.
My husband grew up in a very, very poor family, and rarely got toys and treats other than at Christmas. So every couple of weeks, I bring home a treat for him. Maybe it's a bag of salted peanuts (he loves them, but never buys them for himself), maybe it's a coloring book, maybe it's a miniature red wagon (he uses it to store his remote controls, it's just the right size. The point is, it's something that's completely unnecessary, and a complete surprise. It makes him feel cherished.
