Ha! I love that you asked this! About two or three years into our marriage, my husband and I went to the movies, and when I went to buy snacks, he asked me to get him a Coke. But the theater only had Pepsi, and I realized that I had married someone without knowing whether he was willing to drink Pepsi if there was no Coke available!! So yes, this is absolutely worth discussing…and then remembering, because I can no longer remember the answer.
