I scared the living daylights...

I scared the living daylights out of the Mister the night before last. We'd been asleep for about an hour and I had got it in my mind that he was working nights and that I was alone in bed. So when I had to get up to pee I turned on the bed side lamp as I usually do when I'm alone at night and have to get up, I then sit up in bed and just as I'm about to swing my legs over the side I see someone moving right next to me. Of course it was the Mister but in my daze for a split second I thought it was an intruder and before I could stop myself I looked at him and screamed at the top of my lungs, and I mean at the top of my lungs! He got  scared, I got scared, my heart was pounding so hard it took me good few minutes to get over the shock. After a few minutes we went back to sleep and the next morning as the Mister came in to say good bye to me before leaving for work he was still laughing about it, asking me what happened - same thing when he came back from work last night. I open the door and he's standing there grinning at me asking me once again to explain what on earth went on that night.
