Do not give the sheer pleasure to those who have hurled you personal insults by giving one back or doing something along those lines. It is only meant to weigh you down. And you have much better things to do than indulge them with your time. Firstly, they don’t deserve it. Secondly, you’ll only be wasting your time focusing on them. Become so thick by being clear of who you are that those kind of words will not have an effect on you.
