Found this in my call logs, I was not in the house to hear the phone ring.
The length of the call indicates they let it ring only two times before hanging up.
It's been more than 25 years since I have been to Southeast Texas and Louisiana, and the people I knew then would have left a message. That is, the ones who are still alive.
