Way back in nigeria, on my to school one day, i heard a boy calling a girl making a familiar sign of sisssssss, sisssssssss, the girl look back to see the boy, and hiss, the boy continue callling her, then the girl look forward and saw a mistress also trekking to school, the girl ran to her and said, EXCUSE ME MA, EXCUSE ME MA, IF SOMEONE IS CALLING SOMEONE, AND SOMEONE DOES NOT WANT SO ANSWERE SOMEONE, WON'T SOMEONE, LIVE SOMEONE ALONE? then the mistress answered and said, YES IF SOMEONE IS CALLING SOMEONE AND SOMEONE DOES NOT WANT TO ASWERE SOMEONE, SOMEONE WILL LEAVE SOMEONE ALONE.
This is a dry joke i swear
So what does the joke teach us?
