I understand where you are coming from, but priming a water pump & using a phone are 2 very different things. The teenagers in the video have used a phone a million times, they've never even seen a water pump. Regardless of experience, placing a phone call requires actuating a series of 10 numbers. The numbers are plainly marked, the wheel only gives to 1 direction & there is a hard "stop". So, I have no problem with the youth of today not understanding old technology, but not being able to figure out a phone is a little scary IMHO.
