-Are you going to sit down to read today?
-Oh. I have been reading for so a long time that I am exhausted!
-Yes, too long. You have been reading, or to speak plainly, staring at the book for a whole hour. Great!

-For example?
-Hmm, well! Columbus discovered American continent first.
-Really? Why do we not call America by his name then?
-So, I think He didn't want it.
