Misunderstood

I remember when I was small, I used to sent to my aunty's house so she can look after me. I was playful at that time.
One evening, my biao ge is washing his car, I joined him. Then there is a lorry selling gas passed by. I pretend to be a mechanic asking the lorry to come....oops...they reli came, so no choice but to apologize to them.
Yesterday, the ice-cream guy look at me, I looked at him. He nod his head, I shake my head.
These people knows how hard is it for them to earn money.......
