Puzzling Behaviour

Perplexing.  At times, disappointing.  Various scenarios with similar outcomes.  Acquaintances saying they will call.  Others announcing they would love to get together.  Mentioning plans to meet up.  For coffee, a walk, even weekends away.  Then nothing.  Days, weeks, months go by.  Not a word.  Initiating the discussion without following through.  Forgetful?  Too busy?  Life challenges?  Or simply empty gestures?  Puzzling behaviour.  Often observed over the years.  Still working on not getting too attached to the outcomes of these conversations.  An ongoing personal challenge.
