I got his tools out (yes. A life threatening choice already.) and started putting it together myself.
When I'm almost done, he comes out of his mancave, after I dunno how many beers, and starts laughing at me. He then proceeds to try to show me how it's done. Remember, I was almost done at this point.
He stands up the bookshelf, ignores the instructions, asks me what to do with each piece 3 times, tells me my instructions are terrible, and puts the shelves on crooked. I told him he was drunk and needed to let me do it.
He's now sulking because I also told him I wouldn't put his tools away. I could lie and say I will, but we all know I never do, I will put them in random drawers throughout the house so we never know where the hammer or screwdrivers are.
Buuuuut, my shelf looks great now, and I have space to organize and declutter the living room.
