So, My wife and her daughter look remarkably alike same height same build, They get mistaken for sisters all the time, well It was a long busy day, and we were at home, and I came around the corner,
and saw my wife standing there, and gave her a nice big playful smack on the ass, Only it wasn't my wife, they were both wearing extremely similar outfits.
She just laughed it off but my wife is really pissed and hasn't really spoken to me since. I think I'll be on the couch for a bit.
(resubmitted with the rest of the story, since I ended without the result it was removed)
Edit : The couch thing was a metaphor, kind of like being in the doghouse, Im' not ACTUALLY sleeping on the couch, We've since talked and she's cool with it, knows it was an accident.
