On superstition, my wife and I have this little ritual before I go flying.

"Be safe," she says.
"Always, always," is my response.

One day we didn't have the exchange before I left the house, and within twenty minutes my phone was buzzing pretty much constantly (I can talk on the phone or I can drive - I just can't do both). I get to a place where I can pull over to see what the emergency is, and you guessed it - it's the wife trying to take the hex off.
