3rd of December

Also known as "Heather Day," this is when you give your partner or romantic interest your sweater. For a crush it's like a confession, but for a partner it shows that you value them above all else. It also represents just how wonderful they are and that you feel your life has been made better by them. They are "your Heather."

Based on the song "Heather" by Conan Gray on his album Kid Krow.

It's the 3rd of December! I better be wearing their sweater by the end of the night
