Electronic C of O copy, nice. Ours was just a standard yellow paper inspection slip; was tempted to frame it but that seemed a little too dorky LOL.
Your wife is right, most people will simply not understand how precious and rewarding it is to obtain that document.
Kitchen looks great! I forget if you have a pantry around the corner? I notice a kind of lack of storage, haha. We way underestimated our storage needs in our design and now live with a bit more clutter than we'd like. Oh well! Life is good.
Gonna take a break from the house finish work? Maybe get some veggies in the ground?
