Even though it’s your one year anniversary, your girlfriend keeps flirting with the waiter during dinner. When he asks for your girlfriend’s number, she shoots you only a brief guilty glance before writing her number on the back of the bill you just paid.

“Can I call you later tonight?” the waiter asks, snagging the paper.

“I’ll wait by the phone,” she purrs at him, then turns to you and says in a flat affect, “I’m going to have to take a rain check on the rest of our plans tonight, darling. Something’s come up.”

Raising a glass, she toasts, “To a more fulfilling second year.”
