How on earth did May Day go from this:

May Day was also celebrated by some early European settlers of the American continent. In some parts of the United States, May Baskets are made. These are small baskets usually filled with flowers or treats and left at someone's doorstep. The giver rings the bell and runs away. The person receiving the basket tries to catch the fleeing giver. If they catch the person, a kiss is exchanged.
