During my many sojourns in the Delhi Metro, I have realized one thing that no matter how much Delhiites are ridiculed, they have some degree of respect towards the elderly. One thriving example of this is the fact that men and women of all ages are more than forthcoming when it comes to vacating their seat for an elderly person. However, from a personal perspective, this trend confuses me besides making me feel good about my city. For starters, apart from the folks who are extremely old and look weathered and worn-out, how do I always know about vacating my seat?
