6/21    You're at work on the weekend or at night, and you need help from
        a co-worker who knows some piece of information you need.
        by what algortithm do you decide wether to call them at home or to
        wait, but then end up waisting your own time?
        \_ If you ok it with this person ahead of time, then it's ok.
           But most ppl when they go home don't want "work" to follow
           them. Maybe you should think of going home, too.
        \_ algorithm, whether, wasting.  kids these days.
