It's a picture of my bag of laundry! I think this yellow bag was a freebie offered by the Sud Zone laundromat on 34th Avenue between 29th and 30th Streets. I question whether "sud" could be a singular. Have you ever seen a sud? Just one sud? I have not. In my world suds depend on each other, one sud's existence dependent upon the next sud. Are we not suds, each and every one of us?
