If someone says that words never hurt then they literally lying, speaking is most powerful tool and the words can prove magical or destroyable. Many times in life many pass comments on us and for that particular moment we surrounded with so much suppression and anger, but one thing is for sure and that is, we have options, so we have to walk on our path, we have to keep an mindset which will not going to influence by the next person, and you said right, we can change ourselves and the behaviour of next person is his/her responsibility.
Wishing you an great day. Stay blessed. 🙂
