Bad Eyesight

Nate wakes me up in the middle of the night.  He's gasping and saying "It scared me."  I look between us to where he's pointing and all I can make out (without my glasses in the dark) is a huge dark spot between us.  Immediately I think blood.  A huge pool of blood on the blankets between us.  Oh my god, which one of us is bleeding?  And then I reach out and... it's Nobby.  I am so blind, I thought my cat- 2 feet from my face- was a pool of blood.  In my defense, it makes a lot more sense to say "it scared me" about blood than about our cat.
