Recently, my mother asked me to drop off some letters at the post office and pick up some stamps for her. Without giving it a thought, I took the letters and purchased her stamps.
A few days later, she mentioned that one of the letters I had mailed was missing a stamp, and asked me if I had put a stamp on it. She had remembered asking me to put a stamp on it, though I certainly had not heard her. So, unfortunately, it looked like the letter, which was a bill of course, would come back marked "Return to Sender for Insufficient Postage". A few days went by and I returned to the post office to picr mail. While I was there, I saw the postmaster and happened to tell him about Mom’s letter missing the stamp. I asked him to be on the lookout for it coming back. It was then that he told me his story. "You know," he said, "I immediately saw after you had dropped the mail off that your letter was missing a stamp. I also noticed that it was a bill for a credit card company. I thought to myself that you have always been kind to me and my partner, and I wanted to return the favor. So, to prevent your mother from getting charged a late fee from the credit card company, I took money from our change dish (extra pennies for folks who need one), and purchased a stamp for you."
When I heard it, I couldn’t believe it. What a blessing that was! I thanked him over and over again for putting the stamp on the letter for us. Then, I immediately dumped(倾倒) all the change out of my purse and into the penny dish in order to help others out in the future. When I got home, I was able to tell Mom the good news. This was kindness karma(因果报应) in action, I believe!

If you need to spend time on the road，it's important to find ways to keep safe on your feet．Don't suppose it's your right of way. Yes，you might be crossing at the right place，at the right time，within the crosswalk area，but you are still exposed to danger. It could be a distracted driver，or a cyclist with a loose sense of traffic rules，so you could still get hurt．You can be in the right legally，but that won't be much help when you're in the hospital.
Follow pedestrian(行人) signals. Just as drivers aren't supposed to speed up to beat a light when crossing through an intersection，pedestrians need to take the same care when obeying their own signals．If the hand is flashing and the countdown is into single digits (数字), stay where you are．Trying to outrun the flashing hand is unsafe，especially as cars try to clear the intersection before the light turns red．
Give drivers enough time to stop when crossing. Don't suppose that drivers will jam on their brakes when you hit the crosswalk signals. Some provinces，such as Alberta, issue （发出）a ticket if you don't give drivers enough time to brake.
Cross quickly. Once you've followed all of the other rules，and it is safe to cross the street，don't then just wander along in front of six lanes (车道) of traffic. There's no need to run or jog，but respect the drivers who respected you enough to stop for you.
