Article: The best family vacation that I ever had was going on a road trip to Myrtle Beach. The trip was for 2 weeks during the March break from school. This trip was probably about 20 years ago so it was before the time of things like portable video games and being able to watch movies in the back seat.2 So to pass the many hours of travel my brother and I had to entertain ourselves and each other. My mum would set the back seat up so that it was our own little playroom. She would pack everything up so that we had a big level area to play in. We would play cards and board games.C When it got to the point where we were at each other's throats we would be sent back to our own side of the seat and would be forced to either nap or read by ourselves until we could be friendly to each other again. I can remember us playing for quite some time when we turned the back seat into a spaceship and traveled around the earth.f Another time we turned it into a kitchen and had a bake-off . But the thing that I remember the most and that gave us many hours of enjoyment was using each other's faces as silly Plasticine and making funny faces. We would see how far we could stretch each other's mouths open, see how thin we could make the other's eye by pulling on it. We would keep going until one of us begged for mercy because we had to give our faces a rest.7 So while I can remember us having a great time on the beach, laughing a lot trying to put the tent up in the rain, what I remember the most of that trip and what always makes me smile the most is remembering the pain that our faces would be in after the trip.g

Article: Once I invited a group of friends round to my house, telling them that I was going to record their speech. I said I was interested in their regional accents, and that it would take only a few minutes. Thus, on one evening, three people turned up at my house and were shown into my front room. When they saw the room they were a bit alarmed, for it was laid out as a studio. In front of each easy chair there was a microphone at head height, with wires leading to a tape-recorder in the middle of the floor. I explained that all I wanted was for them to count from one to twenty. Then we could relax and have a drink. I turned on the tape-recorder and each in turn seriously counted from one to twenty in their best accent. When it was over, I turned the tape-recorder off and brought round the drinks, and for the rest of the evening there was general cheerful conversation--interrupted only by the fact that I had to take a telephone call in another room, which unfortunately lasted some time. Or at least that was how it would appear. For, of course, the microphones were not connected to the tape-recorder in the middle of the room at all but to another one, which was turning happily away in the kitchen. The participants, having seen the visible tape-recorder turned off, paid no more attention to the microphones which stayed in front of their chairs, only a few inches from their mouths, thus giving excellent sound quality. And my lengthy absence meant that I was able to obtain as natural a piece of conversation as it would be possible to find. I should add, perhaps, that I did tell my friends what had happened to them, after the event was over, and gave them the choice of destroying the tape. None of them wanted to--though for some years afterwards it always seemed to be my round when it came to the buying of drinks. Linguistic research can be a very expensive business.
