There are many trees in my garden. One such tree is a mango tree and obviously, there are some mangoes on it. Using the Slingshot I try to get some mangoes. After half an hour there are no mangoes on trees and no mangoes with me.

How come ?

There are two mangoes on the tree. Using Slingshot I got one mango.
Therefore now one mango is with me and one mango is in the tree (note: we do not have mangoes (plural of mango).
