Dear journal, I'm not an outdoorsy kind of girl, but when my neighbor Adelle invited me to go camping, I could hardly tell her I was afraid of bears and snakes and pretty much any wild animal. I had images of waking up in the middle of the night, my tent shaking to the rhythm of growls. I couldn't let Adelle know I was afraid. So, I packed my bags and waited at the door the morning we were to leave. To my great surprise, I discovered that camping isn't at all how I imagined. The park ranger assured us that no bears had been seen in the last five years, and to my great surprise, Adelle's family had a pop-up camper, so we weren't even in a tent. Adelle did get to see my true colors, though, when we were hiking. We came across a snake in the middle of the trail, and I've never run so fast in my life. Snakes aside, camping's not so bad. What techniques could be used to improve this sample diary entry to make it interesting and effective at sharing the experience? Check all that apply. adding reasons why the speaker was afraid adding some dialogue adding more description about what was enjoyable about the camping trip adding more information about bears adding a description of the pop-up camper
