It frustrates me when I”m hanging out with friends and they seem to be more preoccupied with TXTing people who couldn’t bother to show up instead of talking to the friends that are actually there.

David Shipley and Will Schwalbe, authors of the e-mail etiquette guide Send, suggest this rule for TXTing: Are you in a situation in which it would be rude for you to be doing a crossword puzzle? If the answer is yes, then stop texting.
