Good Boy, Marley!
This is a pretty wholesome plot twist that starts with a huge, huge misunderstanding. When they moved into a new neighborhood, they’d always hear someone calling Marley, their name. They didn’t know what was going on at first, but ignoring the calls didn’t seem to harm anyone.
But as the days went by, the OP learned that while someone was indeed calling their name, they weren’t calling for them. The neighbor just happened to name their dog Marley. It must’ve been pretty awkward when someone asked Marley whether they wanted belly rubs or a ride to the park.
