It’s the 143rd day of the year and Mister Rogers often used the expression “1-4-3” as a way to say “I love you.” His reference was to the number of letters in each word: one, four and three.

Carrie Fischer Lepore, of the Pennsylvania Department of Community and Economic Development, said, “Today is just the beginning of a three-day weekend of door holding, thank you note writing, and coffee buying. It’s as simple as that to celebrate 1-4-3 Day.”
