Stupidity?

Have you ever thought you are stupid?
I know it is a silly question! But be honest...

Today I did feel I was a silly person!
To make a long story short, I had a car-crash few weeks ago and the car is still in bodyshop. We had to get a car right away.

We were lucky because Abdy's company accepted to give us a car for a while. We had that silver color car for two weeks I suppose and returned it 2 days ago. Then from yesterday we got a black Toyota car from repair center, because of their delay.
Today I dropped Abdy and Dena to their places and went to the office. When I was finished at 4 PM, I went to the parking place and went right away to a silver car - which was not like the silver one we had for a while- and tried to open the door with the remote. I heared the sound but the door didn't open! NO WAY! I thought. I tried once more, againe and againe for 4 times! Then I realized it was not the right car. It was the black car next to me that made the sound... and YES it was my car, the black car, not the silver car...
And guess what... 2 workerd stared at me with a big smile... I smiled back and thought... 'Yeah I know, I just made your day!'
