Call the Sandwich Police
According to research, if you slice a sandwich diagonally, the sandwich’s flavor intensifies by up to 33%. We can’t show you the research paper because we made this stat up, but it’s true. However, slicing a sandwich diagonally requires a level of finesse that some people, such as the OP’s husband, don’t possess.
Who in their right mind slices sandwiches this way? The diagonal cut is flawless, but the angle is totally wrong! And he didn’t just ruin one sandwich; he ruined both with a single slice! For shame, OP’s husband. You’re lucky your wife didn’t’ call the sandwich police on you.
