Photo Story · Mosquito Trouble
Audio 20 · Photo Story
Read and listen to a conversation about how an invention might have helped someone.
Part 1 · The problem
Leslie: This itching is driving me crazy!
Jody: Look at your arm! Are those mosquito bites?
Leslie: Yeah. Ben and I got eaten alive last weekend. We went away for a second honeymoon at this cute little bed and breakfast in the mountains, but the mosquitoes were brutal.
Jody: That doesn’t sound very romantic. Didn’t they have screens in the windows?
Part 2 · The cause
Leslie: Well, they did, but ours had a big hole, and we didn’t realize it until the middle of the night. What a nightmare!
Jody: Too bad you didn’t bring any insect repellent. There are tons of mosquitoes in the mountains this time of year. Hello!
Leslie: We actually did have some, but it just didn’t work that well. You know how Ben is—everything has to be organic and natural and ...
Part 3 · The solution
Jody: Well, with all due respect to Ben, you just have to bite the bullet once in a while and use the stuff that works. Whether you like it or not, the poison is effective.
Leslie: I agree, but Ben won’t hear of it. You know, next time we go away for a romantic weekend, I’m packing one of those mosquito nets to hang over the bed.
