"A few of my friends like to post several times a day about what they are eating: 'I just ate a Frito pie.' 'I am enjoying a double hot-fudge sundae at home tonight.'

"My question is this: If we didn't call each other on the phone every time we ate before, why do we need the alerts now?"No kidding!
