Glitch in the System

I really thought that I wrote a blog this morning. I remember going downstairs as usual and writing something earth shattering, as usual. At 4 pm my sister called me and asked where my blog was. I said it was posted since 7am. She said it was not. How could that be? I remember doing it. I came downstairs and turned on my computer and lo and behold, it was not there. I guess I am getting old. I wonder what else I am forgetting. Hopefully not my pants.
