About National Memo Day
Each year, we celebrate those delightful little notes you receive from your boss or the “honey-do” lists left by your significant other with National Memo Day. Short for “memorandum,” this day encourages people to write a note to someone to inform them about something. So, put your pens to paper and let someone know something!
