Exhausted

I was hit by a brick of fatigue today. I was so tired that I fell asleep on the floor with my son playing in front of me(its a safe space in his room, he couldnt get out without climbing on me, thus waking me). Well my SO came in and I woke up after he was watching me and he just smiled and took our son the the living room to play. I went right back to sleep right there on the floor and slept for an hour and a half! Not very comfy but it was so hard to wake up!
