It’s polite to:
…fulfill your obligations.
…answer them back right away.
…nod in agreement.
…go with the flow.
…do as you’re asked.
…drink because they are.
…take their call.
…give your undivided attention.
…fill the silence.
…and always be there when they need you.
Then again, no one’s ever done anything remarkable by always being polite.
Be stingy with your time in 2013.
It is, after all, yours.
