It’s rare that I get two days off in a row, but this weekend I have a whole extra day for Topaz to lie on my lap and tell me about her new science project. I seldom understand what she’s talking about, what with her theories and specialized tools. You’d need specialized tools to build robots if you lacked an opposable thumb and the knowledge that cats don’t use tools or build robots. Brilliant Topaz cares not what anyone thinks. She cares only about results – results and fishy treats.
