Meanwhile, the other 10 dudes are just chilling on the other side of the wall, not only because there is a wall in the way, but because they speak a different language than the other 10 dudes so they wouldn’t be able to do the work that they are doing in the first place. Now imagine all 20 dudes are bunched together and all speak a singular hybrid language. That same work load is dumped on the 20 dudes and they are able to knock it out in 1 hour. |
