Mindful

Be careful  when selecting  words to express yourself and your emotions.  It may end up meaning what you never  intended. Understand  your words and it's usage before application;  it goes a long way in preventing and avoiding misunderstanding.  If I used the word "WAYO", rather than cunning,  he would have felt better and still understand  my message., which will keep our conversation  going. 
Be mindful of your words.  Choose words wisely.
