You have 7 seconds after a thought to make a decision, and in my opinion, it all depends on the type of person. Some people don’t think— they react.
The more spiritual you become, the more that you will notice the gap, now that’s not to say you will not still react to something that you don’t agree with, but if at that moment you feel the need to reply as you know the person is wrong or have their facts wrong.
Take a moment to think… will me replying help the situation? If the person is sensitive or doesn’t take feedback very well, no matter how you correct them, it will not go down well.
Many people in my life can not take being corrected, so what I have learnt to do is go along with them.
Now I’m not perfect, I still reply when I know it’s the wrong thing to do, but the more that you can bite your tongue, and keep your thoughts to yourself the happier you will be.
If someone is continually annoying you the best approach you can take is wait until the right moment to give them constructive feedback, there is a better chance of a good response, and your feedback listened too.
