my sister is brilliant

My sister Jes, came up with the idea to give my mom a 70th birthday party. Mom is cool yet neither of us knew how to tell her once the invites were sent and the food was bought that, 'yes, she had to attend'. Jes asked our Dad about it and he only said, "she is going to kill you". You see we planned this party for almost a year and yet no one knew about it until the time came to tell. Our mom would have and did even try to say she wasn't coming. The party was great. Mom only threatened to kill my husband Robert once- he took her picture. All in all it was great food, great company, and mom knows how great we think she is : )
