Just a random post, after seeing an elderly couple greeting each other at an airport after being apart for 2 weeks (a REAL 2 weeks )

One and one is always two,
each alone, here's me there's you.
The sum of being friends is done
to prove that one and one makes one.

And NO, I didn't write it, I copied it from a kids book I read MANY MANY years ago. Can't remember the name of it though. But it included something about three "Strings" being combined to make a rope that could not be broken.
