The tone of a word is hard to communicate when tension and frustration has set in. It is easier to type or text and to let the words flow without reading and checking as to whether they say what we really intend.
How many times do we proof read a text, tweet, update or message before hitting send?
Is it a sign of becoming lazy with words and putting more emphasis on the expectations of the recipient that they will 'know and understand'. Words and their interpretation should never be taken for granted but they so often are. We presume others are more aware of a situation or have inside information or are conspiring against us and we get angry and sad when the response is not what we want to hear, when in actual fact, if the response was said to us in person and we could hear the tone of voice, see the facial expressions and body language, we would know that there is no conspiracy and that people do care.
Words are powerful things, please use them with care.
