  4. 5. Answer #1: he is very short and cannot reach above the 50th floor button. On rainy days he has an umbrella and uses it to reach 100th floor button. On sunny days he does not have the umbrella and can only reach the 50th floor button. Of course if this is a persistent problem, why doesn’t he use a cane on sunny days?
    Answer #2. The lower half of the building is wider than the upper floors. The elevator is interior up to the 50th floor and exterior above the 50th floor. The sun shines through the glass in the elevator above the 50th floor. He is a vampire and must not be exposed to direct sunlight. So, he exits the elevator at the 50th floor to avoid the sun. Direct sunlight is not an issue on rainy days, so he can ride the elevator all the way to the 100th floor.
