I just rang your front doorbell.
You opened the door, but no-one is there.
Except you see these hanging on your door:
“Happy May Day!” I jump out and yell.
(I took this picture recently at a Qing Dynasty Restaurant in Beijing. I grew up with bleeding hearts in our back yard so these brought back many memories. One of which was the guinea pig we buried near the bleeding heart when she (he?) died while our parents were out of town. I remember digging the hole under the watchful eye of a grandparent. On that happy note, have a wonderful May Day!)
