It's kinda bulls*** that I ask for 3 days for my parents to stop by with my nephew (he and my sister moved to Kansas City with her husband) while he was still visiting them; I haven't seen him in about half a year and I asked for three days, called this morning to make sure they were going to bring him by and they agreed. Yet they never stopped by, I didn't get to see my nephew, because it totally slipped third mind and they had to go to Sedalia by 6 to drop him off with my sister. Kansas City is about 3hours away from here
