Peeve: "Oh my god, you have the same birthday as so and so!"

It happens every day!


Think of 25 people you know (living or dead), lower bound:

• You (1)
• Your significant other (1)
• Your parents (4)
• Their parents (grands) (8)
• The family pet (1)
• Your combined siblings (2)
• And aunts and uncles (4)
• Their children (cousins) (8)
• Friends from high school you still know (5)
• Friends from college you actually talk to (5)
• Coworkers you hang out with sometimes (5)
• Neighbors you don't avoid (3)

That's already 47 people. There's a 95% chance that two people in your immediate circle have the same birthday.
