When I was a kid it was a day where if you didn’t wear green the other kids at school would pinch you. Sometimes it got so bad you would start crying. But even if you had a bad day because you forgot to wear green, getting to eat cookies with green sprinkles would make up for it.
When I was a teenager it was a day when I would watch Leprechaun movies.
When I was in college it was a day when classmates would get black eyes because they got sucker punched by someone who had too much to drink.
For most of my adult life it was just another day.
