How are your perceptions of your own actions different from your perceptions of the actions of others?

Perceptions of actions are very biased. You know your own intentions, so you tend to view your actions in light of that. Also, you are present for the entirety of your actions.

You do not know the intentions of others, so you only judge based on what you see, rather than what the other person was intending, or possibly actions that occurred which you may not be aware of.
