Here are some other suggestions for gaining and holding another's attention. Be vividly specific. A specific detail or example proves a general conclusion, not the reverse. A vivid, specific detail is memorable, while a general statement is less credible and easily forgotten. Ironically, most adult conversation and advertising is general.
Children are more likely to be vividly specific and thus more memorable.
When you want to be heard and remembered, characterize your information or request with a vivid, specific detail, example, story or contrasting options. Involve words that relate to the senses. Avoid wearing patterned clothing or other detail on your clothing, especially on the upper half of the body, because it will shorten the attention span of the person with whom you are speaking. Look for the underlying issue. When you are arguing for more than ten minutes, you are probably not discussing the real conflict and are thus unlikely to get it resolved in the discussion.
