Question 1208966
Not a solution the this problem, but:
-------------
Our address at work is 910 Industrial Blvd.
A guy game in, asked for help finding his customer.
Asked me where 909 Industrial was.
Obviously, it was directly across the street.
I told him that, went out front and pointed to it.
He was grateful.
He was driving a "big rig," 18 wheeler.
===============
How can a person making deliveries for living not know about odd and even addresses?
I considered explaining that to him, but decided not to.
Probably then, "How do you know if an address is odd or even?"
There is no lower limit to intelligence.
