On the naming of things

We had an old floor vacuum, a knock-off version I named Not-A-Roomba. Calmer Half noted that it was getting older and more worn out, and the operational noise level and rattling was getting bad enough it was driving me spare. So, he unilaterally declared we were using the proceeds of my latest book release and getting a replacement. (He does this: he checks the budget, evaluates the options, and then takes command and declares we're getting/fixing/replacing things where I've been pinching pennies and waiting until the old one was completely broken down/ worn out/ used to the last dregs. He's almost always right, too.)

Thanks to a sale at Big Box Store, we have an actual roomba now. Though I looked at it and went "Model e5? It's a sergeant?" Calmer Half gave me the sort of grin that tells you he just might have picked that one just to see if he'd get that reaction. 

"The last one was definitely a miscreant E-4!"

Well, this one is much quieter, much faster, and it works. Everyone (except the cats) is happy. 

However, when it came time to refer to it while chatting with friends, I started typing Actually-A-Roomba. That lasted about two mentions, and then I gave in. "Dear, mind if we name this one Roomba-Actual?"

"I was going to name it Roomba-Six, but that's fine, Love."

Normal in this household might only exist as a setting on the washing machine, but it works for us.
