Back in elementary school in one of my friends classes there was this computer with an educational mario game on it like mario chess and stuff. He would talk to you as you play but if you walked away for awhile he would say something while idling.
Once they were doing little presentations and one kid was up there dead silent like nearly shaking because they were so nervous. Not a single person talking.
All of a sudden you hear from the back marios voice yell out “Whats-a takin you so long!”. The kid starts crying and runs outta the room
*As in 'friendship that goes back the longest', not the friend who is the oldest. The friendship has to be ongoing to this day - don't count someone you no longer speak to.
