All of us want to be respected and treated well by the others. However, sometimes we have to deal with people who treated us very badly.
When they intentionally degrade you , do not feel sad or miserable for that. Remember the problem is with them, not with you. Bear in mind that is only their selfishness.
Because kind people do not do that. They are not so free that they spend 24 hours stalking others’ business or finding others’ weaknesses.
Even when they think that you really need to improve something, they will find you and have a talk politely. Because they respect how other feel.
They will not do anything that hurt others feeling. They are smart enough to give an advice in the most pleasant way.
