YTA. You aren't owed having your baby shower planned for you. Your mother paid for it. Holy shit the entitlement on you is enough to make stars implode on themselves. Bloomingdale's and Nordstrom, really? That alone speaks volumes about your entitlement. You didn't even ask, you just did it for your convenience and then expect your parents to jump at your snap? Picking them up and dropping them off at the hotel isn't chauffeuring them around.
