First of all, iron your own shirts, what are you 10? Or Victorian dad? You’re giving her an out. And after so many years this is way beyond schoolboy error territory.
That aside, I do have sympathy. My Mrs is similar. No matter where we are going, it’s the same. For years now I have told her, sitting there with my nicely ironed shirt hanging up, that I won’t move a fucking muscle until she is ready. I wait until she looks ready to walk out the door, before I go for a shower. It takes me literally 15 minutes max from that point to walk out the door.
Don’t get me wrong even with me being a guy who knows the right end of an iron and is prepared to use it, most times she still flaps about as I stand and glower.
But, in the past it’s been 30 minutes after I got ready, now I have reduced that to about five. Still does my head in.
You need to take every bolt hole away. Iron your shirt, comb your own hair and stand there knowing she has fuck all to throw at you.
Won’t stop her, but at least you can say, you have no excuse, standing there all lovely amd spick and span.
