Last weekend (2 days ago) I (87M) replaced my wife’s (14F) staircase (oak) with a big old piece of cardboard (perforated) that I found in a dumpster behind Long John Silver’s (2.3 stars on Yelp). I walk up and down the stairs completely fine, but my idiot wife keeps falling right through the damn cardboard! I told her that she should be appreciative because it took a lot of work (labor) to haul the cardboard into my piece of shit car (1996 Hyundai Elantra) but she keeps berating me (bringing up the fact that I’m a bastard). AITA?
