I don't know how it got in the house, but it did.
I really have nothing against spiders. I never kill. But if they're in my house, they go outside.
However my surprise was when I compared it's size to (now named) Daquiri out of curiosity:
If they had the same water/land advantage, they would definitely be formidable opponents against each other.
Anyway, I let it out, and almost every single time I tried, it ran like heck back to my door and stopped right in front of me. It IS pretty cold, so I felt bad, but eventually it stayed outside. lol
Thought I'd share my gigantic uninvited guest.
