My wife curls up in the passenger seat of my truck?

she and i are splitting up, but we went out shoppin together the other day so i could find running shoes for work and i even helped her put on and try come stilleto heeled boots. While we were sittin in the drive thru for starbucks, i noticed she was curled up in the passenger seat while she had been talkin to me with her knees towards me, she crawled over me to order and was literally on all 4's over me
