Two boys, one with a yellow and orange ball, play in some water in front of a field.
Two boys are throwing a ball to each other after a rainstorm.
Just because they are playing with a ball does not mean they are throwing it to each other.  Just because they are playing in water does not mean it is after a rainstorm.
