What's the last thing people typically say when leaving the house for the day? Generally, people tell their loved ones that they love them.
"Goodbye. Have a good day. I love you."
Why do we all do that?
It's because we all know that there's a viable chance that someone isn't going to live through the day.
And who would want their last words to their significant other before they get run over by a bus to be, "Goodbye. Have a good day. I like peanut butter toast!"
