The act of dumping a glass of water on someone while they are sleeping is not cute or funny, but instead can be dangerous as it can lead to the person being woken up by the cold water and consequently being unable to get back to sleep.

Is the statement "Its totally cute how my monster of a brother would dump a glass of water on me while I am sleeping just because we are in a prank war" false? Yes/no/unknown
