Unbelievable
Imagine this: I’m sprawled on the sofa the other day, staring at my fully illuminated Christmas tree (it’s a rare occasion I have one), a glass of Islay malt in hand, talking to myself moderately … When I squint my eyes, the little bulbs all over the tree turn into mega-stars of some distant galaxy …
And then I notice this tiny, dark speck against the background of the white wall, suspended in the air, between the glass-adorned twigs. I stand to inspect it, and there it is … a baby spider, right in the middle of a barely noticeable translucent web, gleaming in the Christmassy light. No doubt it had travelled in the tree, dormant for winter, before the warmth brought it back to active life.
Rational as I am, I can’t go on ignoring its company, I’m getting superstitious. What shall do about the spider? Please help! basia_t, you seem to be knowledgeable about all sort of creatures around the house. What would your mother-in-law say?

On no account kill the spider! I am not a superstitious bloke, I just like spiders. They are just useful little creatures – they eat those annoying flies, for example. And all this talking that they are slimy, ugly, etc is simply not true. I hope it is not already too late, when I am writing this.
Hm…
I don’t really know what my mother-in-law would say or do. And me? It depends on my mood actually. Most of the time I wouldn’t care. If the creature I see is harmless and won’t eat or destroy anything in my house, I let it stay where it wishes. However, there come Saturdays when I’m in a “cleaning frenzy” and all the spiders get sucked up by the vacuum cleaner.
Is it of any help to you? :)
Thank you, caring and slightly-less-caring souls. Unfortunately, it hasn’t come out since you posted your responses. Two things could’ve happened – it either went back to sleep, or left the tree and hid somewhere in a crevice, hoping for better conditions to live in. I’d rather it stayed in the house. I’ve already had one for a year, living by the bed, protecting me from other, ghastly, creatures. I wonder if they can mate, the two, one from the forest with the other, domesticated.
