Appreciate people who treat you well for no reason, there are few of them, believe me.
Everyone around us can smile at us, but not everyone needs to be allowed close. Many are nearby only because it is beneficial for them, because of some blessings in life. And there are people who may not throw themselves around our necks or get into our souls, but they really treat us kindly. And such people need to be responded to with the same kindness; you cannot spit in the soul of a person who values you.
