Whats App?

I was with my daughter while she hunted for a new car. I tagged along, the older father figure who knew what was what about cars and wouldn't take any "one careful owner" nonsense and also knew what was beneath the bonnet......you get the picture. Can't drive actually and don't know difference between a gear box and a crankshaft. Anyway, picking the car the sales guy arranged finance and said "I'll whatsapp you when I get the answer" My daughter seemed to understand! Me, I didn't have a clue. The world has left me behind!
