It’s a well-known math fact that the sum of two even numbers is an even number and that the sum of two odd numbers is also an even number. It is generally believed that the only case in which the sum of two numbers is an odd number is when one is odd and the other even.
From careful observation and a colossal amount of personal experience, I have found what I believe to be the one exception to this otherwise simple rule. The ramifications of my discovery are staggering to say the least, and the practical applications are countless if not more.
The exception is: clean but used socks. No matter how I add them up, I always end up with an odd number of clean used socks.
Even more surprising, this is not the reason why I am The Regular Oddity.
