This happened three years ago:
My roommate and I are on our way back from the store (I am driving us in my car) when we see an assisted living bus sideswipe the living crap out of a parked pickup truck. It is almost like it is happening in slow-motion, and it makes a loud grinding noise. My roommate and I just sit there with our hands on our faces in disbelief.
I memorize the license plate number and the company written on the bus, but because my friend has to get back to our apartment to meet up with her mom and catch a flight, we have to leave immediately. I drop her off and immediately go back out to where the truck is. It is still there, so I write a note explaining exactly what happened, leaving my secondary email address in case she needs to get back to me for something. I am not sure how that kind of thing works, but if a witness is needed, I want to be available.
That night, I get an email asking for my phone number, and I provide it. The owner of the truck has called to thank me personally, and we have a nice conversation. She wants my mailing address to send me what she says is a “small gift card,” so I give her my dorm room mailbox address.
Cut to a week or so later. She mails me a nice letter saying that the company’s insurance paid for the repairs, which would have been about $2000 and a lot more of a hassle had I not written my note. She also gave me a gift card. I am expecting $10-20, but much to my surprise, it is $100! That card gets me out of a few tight spots, and even after I use it up I keep it in my car, where it still is today.
I’m terrible about getting back to people, so I never did get back to her, although now I feel like looking through my email and seeing if I can find her and let her know about this website. If she ever reads this, I’d like to say “thank you so much for your generosity, and I’m glad I was able to help you!”
