I don’t know if I’m weird. If I am, my mom is too. Because she taught me this. But I haven’t heard anyone else talk about doing it. On May Day, we leave flowers on a neighbor’s doorstep, ring the doorbell, and run. My boys are old enough to do it on their own now. Yeah, last year I did it with them. 
They did a great job! I’m not sure the neighbor was home at that precise moment, but that didn’t matter to the boys much. They got good practice ringing and running.
Happy May Day (a little late)!
