You know you're a nurse when...
you walk to your child's room as she wimpers,
catch of whiff of something you've smelled 10,000+ times before,
can diagnose it instantaneously from that one whiff (chunky, orange-brown puke, 300ish cc's),
turn on the lights and---ding! ding! ding!---see the chunky, orange-brown puke everywhere
and think to yourself,
"Dang, I'm good!"
