This is a nice home just across the street from the church.  Every home has a locked gate in front of it.  Beyond the locked gate there is usually a tiled area where they park their car or bicycles or motor bike or use it for storage or a patio.  The tile is always spotless.  In the evenings they wash the tile down with buckets of water.  When we go to a home we stand in front of the gate and clap and wait for them to come greet us.  Once in awhile a home will have a buzzer, but not often.
