Mathew 7:12
So whatever you wish that others would do to you, do also to them, for this is the Law and the Prophets.

Luke 6:31
And as you wish that others would do to you, do so to them

Listen to me
1. If you hurt someone, no matter how long it takes, apologize. People don't forget how you made them feel.

2. If someone does you a small favour, thank them.
Everyone wants to feel appreciated.

3. If someone takes time out to do something nice for you, make sure you show gratitude.
Everyone is busy nowadays and not everyone cares.

4. Most people are very emotional. So, remember, a few negative words can easily break someone's heart. So, think before you speak.

5. Don't ever disrespect something that means a lot to someone. Destroying people's precious moments in life is vile.
Some only have those memories to live with.
