Joseph Gatt I didn't know that a "Hugging Day" existed, Mary Jo. Turns out however that you are 100% right (as you often are) : the 21st of January is indeed "International Hug Day" since 1986! The day even has its very own website: https://nationalhuggingday.wordpress.com/
From Canada, another cold day -21 degrees feeling like -30 at the moment 5:19am.
