Water

For sure you pick up water "ZDRAVO ZA GOTOVO". And how you react if happens damaged pipe or something similar? In this case you are without water some time. Probably you handled this situation on normal way if you are prepared. But, can you imagine that you are in bath (with a lot of soap) or on toilet and water just stops to run?
What is your reaction?
A. you are peace full
B. you are angry
C. you are happy because this is not first time..this is fun

If your answer is under B., please be happy because you know that water will come again. Try to imagine how much people don't have water. This is luxury.
