DS3y11m doing the antonyms with me reaches the word "cheap"

Myself - Do you understand the word "cheap"?

DS- Oh yes,I do.

Myself (sceptically) - Well, explain the word.

DS - You get things cheap(er) at some shops.

Myself - When you say cheap you mean you pay more or less ?

DS - Less of course.Like at the Millitary Shop (I purchased some stuff at the Army Canteen in India before relocation - 8 months back).Or even the 2 $ shop where I got my Green car with a left hand drive.

Myself (almost falling off the chair) - Well, ok,I bet you don't know the opposite of cheap.

DS - It's "expensive".

I fall off the chair.

Moral - Never underestimate your child especially a gifted one .! & 1 make 11 which is a lot more than 2.

Enjoy
