Six. A finite number. Definitive. While it’s more than one, it’s a singular entity. Six. Complete logic and order. Monochrome. You know exactly what you’re getting. Six.
On the other hand, half a dozen is ambiguous. Do you have exactly six, or do you have a little more than five or slightly less than seven? There are multiples with half a dozen. Is there chaos? Were there more and now you’re on the downslide? Or are you on the upswing, gaining more and more? Assumptions are made with half a dozen, but they depend on the context. Do you see potential or failure? And while one person may assume a positive grouping in half a dozen, another might see a doomsday prediction. Dichotomy. Half a dozen.
I asked for six. Half a dozen were served.
