Memory Problems

I'm sure I've got memory problems I can't remember what my Dad told me saturday about today because I normally meet him in a pub down town about 6pm but on saturday he said "Now I'm on the sick, I can see you early on thursdays" and I can't remember if he said that he'll see me at an earlier time today. I'm sure if he did I would of put it in my calendar on my phone for future reference. But knowing me maybe I forgot to note it in, just have to wait and see if he turns up at 6pm.
