On a dry and cold Friday afternoon lastOctober, Sharon Seline exchanged text messages with her daughter who was incollege. They "chatted" back and forth, with the mom asking howthings were going and the daughter answering positively followed by emoticons(表情符) showingsmiles, b-i-g smiles and hearts.
