Role reversals are an obvious truth of growing up. Just as elders took care of you when you were a child, it is your turn now to look after them. Taking care of the elderly is more ways than one is like looking after a child, however, it differs in many subtle ways too. It takes great compassion, patience and love for such a task, to execute it to the perfection. The elderly need a companion because with age, they become incapable of looking after themselves and need assistance.
