In my memory, May Day means lilacs. There was a huge lilac bush (anyway it seemed huge to me) growing by the front porch where we lived when I was in grade school. I'd clip off sprigs of it to fill May Baskets (Dixie Cups covered with foil, I think) to take next door to Mrs. Younger and across the street to Mrs. Matthews. Hang the basket on the doorknob, knock or ring a doorbell, try to hide, .....
When we moved to a bigger town, we still had lilacs, and also when we moved out of town.
When B and I got married, there were lilacs growing out back.
This year, for the first time I can remember, there haven't been any lilacs blooming nearby. The hard freeze in April took care of that. Ah well, next year they will be appreciated even more!
