The expression, "I was looking for you to stop by" was used by the older generation. A rather amusing scene to ponder. Was the person standing on the stoop with binoculars panning the horizon? Were they sitting in that favorite chair by the front window jumping to attention at each passing auto? Why would one look for a someone to come just on the notion the other person might choose to visit that day? So many unanswered questions to ask the one that never arrives.
