Beyond Tired

I'm so very tired, physically and emotionally. I can only sleep 3 to 5 hours at a time right now. I'm fairly sure that after a day with my grandchildren that will change though. They will wear me out -- in a good way. I'm having trouble retaining a thought and then verbalizing it. It sifts through my mind like so much sand in an hourglass. I know that will get better in time. Right now, I'd really like to curl back up and go back to sleep for a bit. Instead I'm about to head for the airport. I'm really looking forward to seeing my son and getting a hug from him and the children. I miss them.
