The host thinks I'm sound asleep in the room next to her but I actually left in the night and have booked into a hotel across town.
I have a strong and irrational fear of harvestmen spiders. I arrived late at night, brushed my teeth, said goodnight, then just as I was preparing for bed I realised that there were harvestmen all over the ceilings, walls and next to the nightstands. Maybe about 9-10 of them at a glance in a very small room with a narrow bed, but probably a lot more hiding. I have a very strong reaction to them; they make my skin crawl and give me extreme anxiety. There's no way I could sleep in the same room as them. Not a chance. I know they're harmless but it's not about that.
Was I being unreasonable to leave in the middle of the night without saying anything? I don't think I had a choice...
I also have to explain myself in the morning as she'll wake up and realise I'm not there.
