This usually happens to me, that too when I am almost done with my trip, I used to struck up with people asking for lift to a place which is quite long from my destination. But I got used to drop them at their place and return back in the same path I have driven to reach my place which I would have crossed already once!! At times the people whom I drop gets surprised when I go back in the same direction from which they came with me, or in other situations they used to get overwhelmed when they come to know that I am travelling for them and not on my destination!!! This makes me happier, even little amount of gas is used I am always happier when I drop them and smile at them while they thank me !!!!! Thank you for giving me a chance to share!!!!!!
