We often find clumps of black fur on our kitchen floor. It seems that Robb steps on poor Linguine's tail with some frequency. Robb cannot feel his feet to know that he's standing on her, and Linguine is too polite to protest. Linguine must squirm out from under his shoes, and we only realize this has happened by the impressive hunks of torn-out fur.
Likewise, when Robb and I are kissing, I often have to avoid being stepped on. Because Robb gets no neural input from his feet, his body often thinks that he's losing his balance and then compensates for this perceived lack of balance by doing a little tap-dance routine.
Asking your sweetheart not to step on your feet sort of kills the romance of the moment.
