Shapes

Jay: How's the RS coming?
A.: Great--in the event that I'll need to point out to someone that the yellow triangle is bigger than the green square, we are all set. I've got that down.
Jay: Well, colors might come in handy, if we go shopping. You could say, 'I'd like those blue jeans.'
A.: Except that I don't know how to say 'I'd like' or 'jeans.'
Jay: Good point.
