Have you ever asked yourself why people often have trouble (learn) English? I hadn't, until one day my five-year-old son asked me there was ham in a hamburger. There isn't. This made me realize that there's no egg in eggplant either. Neither is there pine apple in pineapple. This got me thinking how English can be a crazy language to learn.
For example, we can get seasick at sea, airsick in the air and carsick in a car, but we don't get homesick when we get back home. And (speak) of home, why aren't homework and housework same thing?
Even the smallest words can be (confuse). When you see "WHO" in a medical report do you read it as the "who" in "Who's that?" You also have to wonder at the unique (mad) of a language in which a house can burn up as it burns down.
English (invent) by people, not computers, and it reflects the (create) of the human race. That is why when the stars are out, they are visible, when the lights are out, they are invisible.
