The Water Fight<br>Danny and Janet shared a bedroom. There was a bathroom connected to their bedroom to get water. One night after they went to sleep they got into a water fight. They went at it and soaked each other. Even the curtains were dripping when they mother looked in on them.
Danny and Janet had the water fight after they got up in the morning
The story doesn't say when they had the fight just that it happened after they went to sleep.  Could have been first thing in the morning.
