Read the text about Sam's camping trip.
Have you ever wondered what land of person you really are? I now I have. At one stage I considered
getting family and friends to say how they d describe me I knew my brothers would be honest, but
maybe I wouldn't like their answers! On the other hand, friends might not want to say what they really
Anyway. I finally got my answer when I went on a youth club camping trip to the coast last month. It
was the end of spring, so temperatures were still low and were going to stay in tents. I'd never been
camping before I didn know what it would be like, but I wagined the tent wasn't exactly luxury
living inside However, I decided to try and have a good time, and not give up immediately. After we'd
amived and set up our tents, we tent on a hike through the mountains. The scenery was spectacular but
I wasn't really looking My feet were hurting and my ears were freezing. I had a headache, but I didn't
say anything I smiled at everyone, and I was patient and polite and I just kept walking
When we got back to the campsite, we had to light a fire and cook for ourselves No-one really knew
what to do but once we d all agreed to help each other, we eventually made our dinner Not the best I'd
ever eaten, but at least it was hot! Then we got into our sleeping bags – for the coldest night I'd ever
experienced Everyone was too tired to talk and fell asleep quickly, but I hardly slept at all and kept
walang up feeling frozen I was really glad to get back to a warm house at the end of the trip!
So it wasn t the greatest camping trip even but it confirmed some things that I'd always thought about
myself Now I can truly say that I'm determined easy-going and patient - and after this trip. I've even
become passionate about camping!
