As I’ve mentioned, my wife and I both graduated from Miami University. Miami is said to have one of the highest instances of alumni marrying. 14% of alumni have married another Miami grad. To celebrate this, they send us “Miami Mergers” a Valentine’s Day card each year. The school’s colors, red and white, lend itself to Valentines (as do the initials, which create a lot of “Me and yoU” puns).
I think it’s a neat tradition, and am glad to see it each year.
