According to my mom, my grandmother left her two pieces of advice:
“Never carry a package by the string”, and “Never trust a man named Doc or Whitey.”
My grandfather had his own sage words, too, like “Never lose altitude unneccessarily.”
Now, after bitter experience, a splitting headache, and a day when I was three and a half hours late to work, I have my own piece of advice to add to the family wisdom:
Never, ever drink Scotch and Grappa on the same night.
