A primary school class has just returned to school after the summer vacation. The teacher asks them, one by one, to come up to the blackboard and draw something exciting that happened during their holidays. First up was Jimmy. Jimmy draw a series of diagonal lines across the blackboard. What's that supposed to be Jimmy? asks the teacher. Well, Miss, we were out for a walk and it started to rain so hard that we all got soaked instantly, and this is a picture of the rain. Very good Jimmy says the teacher.
Next up to the board was Sally. Sally drew a series of jagged lines down the board. What's that Sally ? Well Miss, we were out for a stroll in the forest and suddenly a thunderstorm came up and the lightning struck several trees, and that's what these jagged lines are. That's very exiting Sally, well done.
Lastly Bobby goes to the front and draws a single dot on the board. The teacher asks what's exciting about a dot, Bobby?
That's not a dot, Miss, it's a period !
Well then, what's exiting about a period ?
I don't really know, Miss, but my elder sister has just missed hers and the entire family is excited about it.
