When I was little, I remember going to my neighbor Joyce's house and leaving a little flower basket on her porch. I would run up there, ring the door bell and then go and hide and wait for her to open the door, then I would come running out screaming HAPPY MAY DAY!
I didn't even know the meaning of it, but I just loved that day. I would go pick the flowers (weeds) myself and put them in a little something. Afterwards she would braid my hair in french braid piggy tails and we would spend the afternoon together. Joyce was my best friend when I was little. I always hung out at her house and I guess I didn't realize it until I started thinking about May Day, but my memories of that day always included her.
I now realize what May day is, and it's actually a rather important day although it's not very celebrated. You can read more about it here.
