Bonus thought (boy, is my brain burbling brilliance today...or just wandering uselessly...)
A friend who just got a cell phone urged me to call, "especially on nights and weekends!" This idea of financially beneficial times of the day to talk is odd to me: a conversation commenced at 8:59 is costly, at 9:00 it's free. Quantifying speech that way just seems wrong. The thing is, I'm tempted to call people when the clock ticks 9 just to wallow in the vastness (like the woman in the ad who calls her husband's phone just to get him away from the remote). And then I thought, imagine if prayer were said to be best on nights and weekends--would we pray more earnestly or confusedly if there were certain windows of time to talk to God?
