I'm working on a project, which is writing and illustrating a children's book for age 4-6 now, the illustrations are going smooth, but i have a problem with what text to put in. my story is that a boy goes to a shopping mall, gets lost. a sales clerk finds him, takes him to the cash counter and makes an announcement. his dad comes, and they go home.(sounds dull for someone whose brain is filled with 10 types of physics, but it's pretty good for a child when illustrated :p) anyway, so i'm facing a problem of finding easy words for children. can you suggest some? for e.g. i can't find an alternate for sales clerk. or announcement, or speaker, or microphone, or aisle. help!
