1) Don't text or glance at your cellphone when you're talking to someone.It's no wonder that many workers, especially those not experienced with face-to-face interaction, prefer to stay home and telecommute.
2) It's wrong to look away too soon or stare at someone too long. "Holding eye contact works best for 7 to 10 seconds in a one-on-one conversation, and for 3 to 5 seconds in a group setting."
