Mom: do you want anything
Ross: i want alot of things, i want a good phone
Mom: i meant from the supermarket -_-
Ross: oh, some chips would be nice
Mom: and besides, i dont think youre getting a new phone xD
Ross: what? why?
Mom: how dont know to take care of one
Ross: thats not true, this one fell on the ground from my jeans
Mom: whatever Ross.. 
Mom will buy some chips for Ross. Mom won't buy Ross a new phone as he doesn't take care of the one he owns now.
