Just two weeks ago, I was about to cross a busy road when I noticed an old grandpa with a heavy load on his head just a few meters from me. He looked very weak. A few minutes later, I realized I'd forgotten to cross the road. And he'd seen me looking at him.     I love my grandparents so much that whenever I see any old people I won't forget to smile at them. I couldn't let go of this grandpa, either. He came near me and handed me a note on which there was an address. I showed him the directions and said he would need a taxi as it was 3 pm on a hot summer's day. Anybody would faint dead in this weather and I didn't want him to walk all the way. But he looked disappointed.    I asked where he had come from. He replied weakly that he was from Chidambaram, about 240 kilometers from where we were. I was shocked because he looked like he could not even take 2 steps without falling. I called a taxi immediately and asked the driver to drop him at his place. The grandpa wasn't ready because he had no money. I paid for his journey and asked the driver to drop him off safely. When I turned to look at the grandpa, who was leaving, tears filled my eyes and I didn't want to leave. Memories of my grandparents flashed in my mind, making me feel like crying. I said goodbye to the grandpa, and some happy tears dropped from his eyes. What was the old man's purpose in coming near the author?
To ask why he was looking at him. To ask him for directions. To get him to call a taxi for him. To borrow some money.
