If you needed proof that I have my phone on me at all times, well, here it is. Yes, even when I’m dressed like a lobster and wearing fake red wayfarers in a dive bar, lurking around creepily. It’s still there. (Except when I lose it, which happens about once or twice a year.)
The other exception: I have a strict no-cells-at-the-dinner-table (same goes for brunch, etc.) policy. Good food and company are too precious to waste.
