I'm a skeptic, but this is amazing. How can you explain this?

When the volcanic eruption of Mt Pinatubo devastated our area, we had nowhere to go and nowhere to run. We lived without electricity and we had to fetch water from very few major water tanks. One time, while travelling, the lahar flood swept the bridge downriver and I had nowhere to go. It was night and it was raining hard. There was no way I can cross. I was losing hope when this man approached me and offered his home for me to stay. I was skeptical at first, but I agreed eventually when I saw there was no way I could go home. There were no hotels or lodging houses there. The whole family gave me a warm welcome. To make the story short, I went home safe and sound the next day. I have never forgotten that man who had helped me that night. The amazing thing is that now, it's my turn to help him. After years, more than 8 years to be exact - we meet again and now - he has kids and his kids are under my care. I will have to give them the best that I could. Isn't it too much of a coincidence ? Strange things happen in this world. What do you think of this? Did something similar happened to you too ? Is this what we call karma?
