I like to understand why the hell my maid of honor decided to throw my bridal shower...picked the date and left me with all the work because I am a stay at home mom and I do "nothing"!!! Oh my god I blew up on her! Since when the hell do I sit around and do nothing! I am going to school full time online, plus dishes, cleaning, laundry, and taking care of three dogs plus raising my 9 month old son who is into everything...yes let's try and add planning a whole damn bridal shower because I do "nothing"!!! Who else would be pissed off or has heard that before? And what did you do?
