Stupid...

我变笨了。

Case 1：

We were in a Chinese restaurant and a waiter came to take our orders.

Kelly: 要一个蚝油芥兰。

Waiter: 对不起，我们今天没有。

Me: 那就清炒芥兰咯。

Waiter: 我们没有的是芥兰，不是蚝油。

Me: .... .... .... ....

Case 2:

I went to Coles one day, and saw a label said "Muffins-- buy one get one free". And at the very bottom of the label, it said "save $4.00".

Then I was thinking："Hmmm.... save two dollars.... 那原价是多少呢，是不是一块还是两快啊？"

I looked up and down for the original price and found the price label said "Muffins-- original price: $4.00".... ....

Oh gosh.... I was so embarrassed with my stupid thoughts..... I couldn't believe that ME as an engineer can be so bad in these simple mathematics.... ...
