When people try to make us feel selfish; it is tricky to understand whether that is true or not. We should discuss this when it happened.
It normally happens when we do not think the way others think and they call us selfish. It is not that how much we recognize a problem that shows unselfishness. It is how much we see that there is no problem and help others to see it that shows unselfishness.
When we offer help to others, we are constructive and unselfish.
