Here's an uncomfortable small world coincidence that took place in Boston MA: When my GM was giving birth to her last child (first one born in a hospital), the other woman sharing the room was giving birth to her first child. Turns out they both were listed under the same name of Mrs.***** * ***** (my grandfather's full name). The other woman's child was also my grandfather's child. He apparently had been living a double life. And that is why I never met my grandfather.
