Ralphie. I can see that after 42 years that the battle of the sexes moves in more covert and subtle nuances and that at 16 years I'm still dealing with trying to get him to take out the garbage--basic stuff. Untrainable male in the house. Hunting Season is the worst.

First we had John Deere equipment and paraphenalia purchases that were only done to bring you up a class level. Please do not over think this. She is just bringing up your status. Even though you found it covert.
A John Deere brings up the social status of a person about as much as having a meth lab in the back does. Both have the same social standing in polite society.
Keyboard issues. This is just stubborness on your part. You bought the thing and now insist upon using it. If you get the good $50 ergonomic one-- good,comfy and carpal tunnel preventative--she would be none the wiser and as a nurse never give it a second thought. (that you would know--nurses are good that way at hiding their all knowing ways to keep the patient's morale up)
Maybe for a normal nurse, I think my DW is a nurse just for the sheer enjoyment of shoving needles into people. She likes it so much I recently found a doll under the bed that looks uncannily like me, with hundreds of pins in it.
Now the Peaches. What happened to " what is mine, is yours part of the marriage."
Peaches destined to a lemonade smoothie are exempt from this rule, besides she has lots of things I never even touch let alone use!
