Quick question: What has happened to general common courtesies?

Do you miss words such as:

• Thank you when you hold the door open for someone?
• I am going to be late when someone is running behind schedule?
• I am sorry when someone hurts another’s feelings?
• No, go right ahead when you have one item and they have a cart full at the check-out line?
• Excuse me when someone bumps into you?
• I forgive you when you apologize to someone?

Have you noticed these courtesies disappearing from our society?  What words or phrases do you miss?
