Same language... different ears

The other day, I was having a conversation with one of our house cleaners.  Our country director and his family were returning from their home leave, and we were making sure that everything was ready in their house.  This is how the conversation went:

Joni:  "Helena,  could you turn on the Air Conditioning today and leave it on for bossman?"

Helena:  "what?"

Joni:  "Turn on the Air Conditioning today at the house"

Helena: "what?"

Joni:  " the Air Cooler- turn it on today"

Helena: "You want me to turn the water on in the kitchen?"

So even though we are speaking the same english language, sometimes we aren't! :)
