  1. Great sign for editing!

    I would suggest adding a colon after “CONTAINER” to introduce the list and changing capitalization, punctuation, and word choice within the list:

    *Asbestos-containing materials
    *TVs, computers, or monitors
    *Oils, solvents, or paints
    *Fluorescent tubes
    *Household garbage
    *Treated wood
    *Car batteries

    The “…punishment could include…” sign would be clearer and perhaps more effective if the cost of the fine was included. If reworded as follows, it would also have parallel construction (changed “caring” and “forced listening” to “caring” and “being forced to listen”):

    “Further punishment could include days of caring for screaming toddlers and being forced to listen to endless hours of bagpipe and accordion music.”

    Separately, I think the list would be easier to follow if the items were alphabetized and clarified:

    *Asbestos-containing materials (drywall, flooring, flues, etc.)
    *Batteries (button, car, A/AA/AAA/C/D, lithium, NiCad, etc.)
    *Electronics (computers, monitors, TVs, etc.)
    *Fluorescent tubes
    *Household garbage
    *Oils, solvents, or paints
    *Treated wood

    The sign would also be more effective if a website or 800 number were included for people with questions.

    Thank you for an interesting exercise. It will be fun to see what others think.

  2. First sign:
    I would love a pet refrigator. They are cooler than alligators (get it? ha!). I’m guessing “refrigerator” was too long, so I would probably just use “fridges” instead.

    Second sign:
    * Asbestos-containing materials
    * TVs, Computer and Monitors
    Please, oblige!


  3. Hi Jane,

    Thanks for your thorough review of the dumpster sign. I’m glad you had a good time with it.

    Of course, you caught all the items I intended: the missing colon, the missing hyphen, and the extra apostrophe.

    I was surprised that you recommended changing “and” to “or” in the bullet point “TVs, computers and monitors” and the one after it. “And” seems more inclusive and therefore appropriate. I would like to know what motivated your change.

    I found your examples of asbestos-containing materials helpful. And the phone number is a great idea. I also like your suggestion about including the specific dollar amount of the fine. For the “further punishment,” I think the sign painter was having fun–and they got my attention.

    Thanks again for participating. You win the prize!


  4. Hi Patty,

    I like your changes, and I’m so glad you asked “Get it?” You made me look twice and enjoy your cool idea!

    I’d put a colon after “The following items are not allowed in this container.” That’s a perfect introduction for a colon.

    You win the prize too!


  5. Hi, Lynn,

    Thanks for your feedback–and Patty made me laugh as well!

    Now you can also laugh at me as I suspect childhood memories are the most likely reason I suggested “or” rather than “and.”

    If fun activities were planned, “and” was used. For example, we could “play for an hour, watch TV for an hour, AND read for an hour.”

    However, if restrictions were necessary (which they too often were), “or” was used. For example, we could NOT “stay over at Susie’s, watch TV tomorrow night, OR get more books from the library.” The “or” gave additional emphasis to each desirable activity being denied and increased the misery.

    Not a concept based on grammatical rules, but definitely etched into my brain! However, I agree with you that “and” could be used effectively as well.

    Have a great weekend ahead!


  6. Lynn,

    I agree with you that “and” works better with the wording and list format of the sign. However, Jane’s thought of changing to “or” has merit. Consider these examples:

    I like ham and eggs. I don’t like ham and eggs.
    I like chicken and fish. I don’t like chicken or fish.

    Sometimes the negative seems to require using “or.”

    Always fun to think through these usage issues with you and your readers.
