I didn't ever meet Dan or Wendi, but I did have some friends in common with Dan. One of those friends told me about "this awful girl named Wendi" that she met at a potluck dinner.
When Dan and Wendi got to the party, Wendi carried her dish into the kitchen. My friends said it looked delicious, and someone asked Wendi if it was kosher. She said no, it wasn't, but don't tell Dan, that she always lied to him about food being kosher, and that she thought it was hilarious that he'd eat it.
Looks like she started that lie at the wedding.
