Every time you find yourself in a judgement space, reheart (not remind) yourself that you have not necessarily been in that person's shoes and even if you have, you may not have had it the same. Be kind, always.
So, could you believe then, that we also pick up on other people's emotions (e-motion = energy in motion)? Just the same as when, for example, you come home in a great mood and it has a knock on effect to those around you.
