Neighbors who call to complain about tenant language??

[Harriet Baldwin]

When a neighbor calls to complain about detached-home tenants swearing loudly, other than saying "tell me more" and letting the caller vent, any favorite phrases I could use to let them feel heard without triggering wounds or having the conversation dragging on forever?  Had a call today that went almost 15 minutes...I need to work on my phone skills lol!  At least most such callers are one-and-done...

Background - we have about 100 units now, mostly single families in the county we live in.  Once a year I get a call from a "concerned" neighbor about the "language" used by a tenant or contractor - usually complaining about "the F word" (why does no one call to complain about "the S word"??).  Usually B- type neighborhoods.

Typical profile of the caller is a long-time owner-occupant (or their sibling) who is distressed by the "loud and coarse language" of my tenants or contractor.  Often the caller is passive-aggressive (doesn't want to give name, doesn't want to get in trouble for turning someone in, doesn't want to talk to the tenant directly).  I understand that change is rough and that swearing offends many people, but as long as the property is maintained and regulations are followed, how is this my (much less their) business?  I just put them in my contact list as "Eeyore who lives near [unit]".
