In advertising it is believed that the better communication strategy is to get your point across without actually having to spell it out to your audience. As such, advertisers often use metaphors to communicate their ideas. We believe, however, that there are reasons and degrees of deviance away from this advertising strategy that are appropriate. There are times when you can use a metaphor to support your idea, but also directly tell your audience how it is.
