The last time

The twins are at a fun age. They are learning to use words better, but still get them a little confused.Kaelin says "remember the last time" I did such and such. She means yesterday. She also asks what Monday it is. She really wants to know what day of the week it is. Jack says he's going to win me when he really means he is going to beat me. I don't have the heart to correct them because I know I'm going to be sad when they stop.
