任給实数a，b定义a⊕b=a×b，a×b≥0ab，a×b＜0设函数f（x）=ln

 Yesterday I was shopping for a few items(物品).With nothing to do at home, my son, who just left university, was ready to go together with me.

As I pushed the basket towards the register(收银机),I checked my items to see how many I had, thinking I might go to the Express Line(快速通道)where the sign said“Ten items or less”.

I started to go to that line and my son said,“Mon, you have twelve items!”I said,“You know, but they’re close.” He said,“Why are you in such a hurry to get home? You should go to the Regular Line because you have over ten items.”

Knowing he was right. I agreed and then pushed the basket to the next line. So I was waiting for my turn there and I was just removing my items from the basket to pay for them when a young man came up behind me in line with two items.

I just left the Express Line because I had too many and now I really wanted to get finished. Again, my son came up.“Mom, he has only two items and the Express Line is very long now. Won’t you just let him go first?”I agreed, and the young man smiled widely and thanked me several times.

It felt good to be with my son and have him remind me not to live a hurried life. Do what’s right and also be kind. I really take pride in him.
