Out doing last minute things for my baby shower with my Mom bc my SIL, the one who offered to throw it... waited til the last minute to tell my mom she basically needed everything. Plates, cups, silverware, decorations... oh and just YESTERDAY asked if my hostesses could also bring a finger food 😑😑😑😒😒😒😝😧 So I guess I get to basically set it up on my own. Awesome 😩🔫
