Always forgive your enemies; nothing annoys them so much.
Not being able to get something that bothers you out of your mind can be very annoying! It can be doubly annoying if that something is thoughts about someone you hate. Wouldn’t it be better if you could forget that person, and so free yourself from these thoughts?
It is often said that love and hate are the two sides of the same coin, and although love may seem too strong an emotion to consider having for a person you hate, there is often an emotional attachment that stops you from just letting go of all thoughts and feelings, as you would for someone you didn’t care about. So, how to forget someone that you have such strong emotions about?
