Spider. In My Bedroom? Eeeek! OK, calm down, man up, get off the chair. Next step?
Well, depends whether I need to use a rolled-up newspaper or a baseball bat to swat it, and whether it's big enough to steal it off me and hit me back.
If it's venomous, it can have the room, I'll find somewhere else to sleep, I don't need to get bitten fighting the fucker, and for all I know, they won't even have an antivenom for it.
It would be strange to have a large spider in my room. It's not like I live in Australia, it's too cold in Scotland for that shit.
We did nearly have a pet spider once: it ran from under the three-piece suite, going corner to corner and waiting in the dark for a while before making a break for it. It kept going round in the triangle for a couple of days, and we did contemplate putting food out for it, and sticking a leash on it while we were busy, so we could take it for walks, as it was pretty big, but we didn't.
