because they will be forgiving and grateful for the slip up, no matter how confused. They don't judge us like people do.
I pulled something similar years ago, but in a human setting that was quite embarassing.
I had a second job, part time evenings and Saturday mornings. I had just started a med that combined an antihistamine with a decongestant. It was early autumn, when the morning sky looked a lot like the evening sky.
I had Friday night off and fell asleep around 6 pm from the effects of the med. When I woke up, my clock said 8:00. The sky had a pink dawn glow. OMG! I had slept through the night and was due at work for Saturday morning.
I rushed into work and saw co-workers doing tasks that I was normally assigned to. I apologized for not being there sooner and said that I would take over. One of them said, "Don't you have Friday nights off?" I said yes, but did not go anywhere Friday because my new med made me tired and I must have slept right through.
Another one said, "But it's Friday. What are you talking about?"
I was totally confused. They finally made me realize that it was Friday evening, just after 8 pm, not Saturday morning at 8 am.
One of them said she wanted whatever I was taking. They never let me live it down.
So, as the spacy Luna Lovegood says in a Harry Potter book/film, "Don't worry. You're just as sane as I am."
