(Games of Endearment) OR (Does Sappiness still live)

I’d like to start out with an explanatory anecdote, then launch into my question, please bear with me.

Approximately two months ago, Mrs. Mastema and I were happily engaged in one of those stupid little arguments that make marriage worthwhile. It seems that in the course of unloading the dishwasher, I suffered a temporary break from sanity and put the plastic spoons, forks, etc. into the same drawer as the silverware/Wal-Martware. I now realize that when this was initially pointed out to me the correct response was abject humiliation followed by begging for absolution; however, as I am not the sharpest plastic knife in the silverware drawer, I decided to question the logic of putting some of the forks and spoons in one drawer, and some in another. Perhaps I was hoping for some “All your eggs in one basket” answer, or perhaps I had decided that I really LIKED sleeping on the floor. I really don’t know. The whole thing degenerated into an evening-long bickering session. Since that evening, when the mood strikes me (every couple of weeks), I’ll gather every plastic utensil I can find and fill the silverware drawer with them, along with a note telling her how much I love her or some such sappy sentiment (<-- alliteration RULES). The first time I made sure that I wasn’t around when she went for silverware, to make sure she found my note before venting her ire in my direction. Now she gets a kick out of something that initially caused an argument. My friends do not understand this. They have been married longer than we have (3 years), and assure me that this sort of thing should be drying up soon. I certainly hope not.
My questions are:

[li]Does anyone else still engage in this type of flirting behavior after marriage?[/li][li]Do you have any examples of other way to pleasantly surprise your SO, or related stories to share?[/li][/list=1]

I did.

Care to elaborate? Especially on the past tense part.
