That would terrify me! I am pretty much ok if I see any type of creepy crawly. And if there is a bit of distance. Wasps however just throw me into mad panic mode. Its silly but the high pitched squeals and screams!
I dont like the idea of a spider big enough for you to hear the pitter patter, yikes!
I suppose it is POSSIBLE that my over active imagination came into play and it wasn't really pitter pattering. But we do get some rather large spiders in our downstairs area sometimes. Last time I saw one I dropped a waste paper basket over it till @sift666 got home. But the basket didn't have the space underneath it that I thought it had. So there was no rescue mission later on, and i had been sweating for hours in case it escaped, all for no reason.
Oh my word, that really gives me the heebers. I am feeling antsy just thinking about it. The other day I caught one that was about two inches across in total and I was terrified!
