Dingdong ditching

Had an "opps" moment the other day...Our hallway/stairwell light is on a timer.  We stepped out one evening and the light was on.  We got halfway down the stairs when it went off.  Each landing has a switch on the wall, so I reached for the switch to turn it back on and...hit the neighbor's doorbell instead! Dashed on down the dark stairwell...fortunately no one was home.  No harm done.  -Carolyn
