I wonder who put three glasses and bowls at the door.

I don't know who put three glasses and bowls at the door, which may have the following meanings:

1. It is possible that the neighbor played a prank unintentionally or intentionally and put three wine glasses and bowls at the door.

2. Maybe your neighbor is testing your reaction and attitude intentionally or unintentionally to see if you will take these things away or show dissatisfaction.

It is possible that neighbors are offering sacrifices to ancestors or gods, praying for peace and happiness.

4. It may be that neighbors are offering sacrifices or divination and want to seek some guidance or prediction.

In either case, you can try to communicate with your neighbors first, express your doubts and concerns, and ask their intentions. If your neighbor's behavior bothers you, you can report the situation to the property or relevant departments and seek their help and support.
