medicine in her future?

Marissa found the thermometer this evening and proceeded to take her temperature and the cat's. At first I tried to snatch it away because she could poke her eye out of course, but then I noticed she actually knows what it's for! She first took her own (see below) then preceded to "take" the cat's-the cat was more interested in playing with it through the window. Just when I think she's trying to be naughty, she impresses me with something she's caught on to. Although she hates getting her temperature taken she knows how to use it!
