Umbrella

It is a raining day again.

So I thought of umbrella. How many umbrella does a person need?

I have an umbrella in car. Whenever going out, if it is raining, I will pull out the umbrella from my car. It is so nice..

I have an umbrella at office. Whenever it is raining during lunch hour or after office hour, this umbrella will be useful.

Of course there must be another umbrella at home. This umbrella is a reserved. So that before going out to either office or other places, there is an umbrella to use. You might not want to use the umbrella in the car if you are walking around in your neighbourhood. And sometimes, you can lend the umbrella to someone else too.

So, my conclusion, each of us should have at least 3 umbrellas.
