Is it right to always to express our feelings even when we know they could probably hurt our loved ones?

It is not right to hurt our loved ones.It is a fact that we are most real in front of our loved ones.All our emotions are exhibited without inhibitions in front of them.But we should be cautious not to hurt them because ultimately they are the ones who will always be by our side.Our loved ones know us better than us.They will forget and forgive but still love and care makes a relation beautiful.
