There are two sayings. "Be careful what you wish for" and "To think it is to create it". When you cross the line with anger in either of these two sayings, your wish just might come true in both.

It is always wise to think before you speak in anger, cause what you say may haunt you in ways you wished it didn't. The wiser choice; take a deep breath and think it through. When you verbally cut someone emotionally the damage is done. In other words, words aren't retractable!
