Growing up, I, my father, and my paternal grandfather all shared the same first name and last name, and all lived within a couple of miles of each other (my father and I obviously lived in the same residence a big chunk of my childhood, and grandpa lived just a short hop away). Our mail (and gosh knows what else) got mixed up all the time.
To make it even worse, I'm one of those people who chooses to use my middle name, not my first name, as my primary name. So while "legal" correspondence often comes addressed one way, sometimes even that gets mixed up, and phone calls are always weird when I answer "Hi, this is Phil" and the person on the other end goes "Oh, sorry, I was calling for $FIRST_NAME". <click>
And to make this whole story even weirder, my maternal grandfather's middle name (which is what he went by) was the same as the first name shared by me, my dad, and my paternal grand-father. So yeah, we had four family members in a very small area, sharing confusingly similar names.
Naming stuff definitely gets weird.
