There is a two-letter word that perhaps has more meanings than any other two-letter word, and that is 'UP.'
It's easy to understand UP, meaning toward the sky or at the top of the list, but when we awaken in the morning, why do we wake UP?
At a meeting, why does a topic come UP? Why do we speak UP and why are the officers UP for election and why is it UP to the secretary to write UPa report?
We call UP our friends.
