"You never know how long your words will stay in someone's mind even long after you've forgotten you spoke them." What you say has an affect on others. The words you choose and how you say them can be taken in different ways. You have control of what and how is said. Sometimes it's best to pause, think, and then speak. Know your audience. If you are asking about something for understanding, yet could be received as offensive, then explain you are asking for understanding. The way you ask will make a difference.
