Should iris have placed the CD back at the coffee station and forgotten the whole thing?

Iris should consider the potential consequences of placing the CD back at the coffee station. If the CD holds important information or sentimental value, forgetting about it could lead to future regrets. However, if it was simply an unimportant item, returning it might be the easiest solution. Ultimately, her decision should weigh her feelings about the CD against the practicality of letting it go.
