The late neighbor's daughter just popped in to say hello and merry Christmas. She and I haven't met for three decades, but she was there when I walked my first steps.
She just found out that the grandson of the previous family in this house, who doesn't live anywhere near here, he's down in the south studying, had just discovered that his friend way over there is the grandson of the previous neighbors on the other side.
They were just texting each other like "so where are you going for Christmas? no way, my mom's from there. wait, your mom lived where exactly?".
