Who can solve this one...
I know a guy, he lives on the 8'th floor of an apartment building.
When he goes to work in the morning, he uses the elevator down to the first floor. Then he walks to his car and drives to work. When he comes back from work, he enters the elevator again to get back to his apartment. Now, the case is, if it's raining outside, he can use the elevator all the way up to the 8'th floor. But when it's dry outside, he can only take the elevator to the 3'th floor. Then he will need to walk the rest of the way up....
Why is this the case?
If you know the solution, please wait a while so others can go figure...
