I think the modern fountain or ballpoint pen is one of the greatest contributions ever made to __16__ happiness.

　 Can you imagine what it was like in the past? When _ 17_ wanted to write a letter, you had to go and find a bird’s _18_, cut it into a point, then keep _19_ it into a small jar of ink. You had to keep on sharpening the point too because it soon got blunt, writing a simple _20_ you letter must have been a main operation, _21__ most of the morning and afternoon.

　 Even __22_, however, was better than cutting words on stone with a chisel, or _23__ them on clay with a stick.

　 Of course, some people enjoy the typewriter these days, __24_ is all right if you know how to type quickly. If you don’t , you spend_25__ correcting mistakes and your letter __26_ a terrible mess. It’s not very easy to carry a typewriter around with you _27__, and you certainly can’t put one in your pocket.

　 Perhaps we’ll soon all have pocket tape recorders and give up writing altogether. We’ll just send _28__ to each other. But __19_ the moment I think I’ll keep my ballpoint pens and fountain pens. What surprises me, though, is that they’re so convenient to use, but somehow I never _30__ to get around to writing all the letters I ought to write.
