Saw this sign and it made me think about the differences between being efficient and being lazy. Sometimes we take our communication tools for granted and communicate the wrong thing. Sometimes we convince ourselves that we are being efficient by using the latest and greatest technology. Sometimes we are really lazy and don't want to expend the extra effort to get it right the first time. Sometimes we just run out of letters. Whatever the reasons, our intended message may not be the message we send.
Communication 101: You cannot not communicate.
Even the unintentional can send the wrong message.
