I just saw a nasty spider in my house and I wondered if it had come inside because it has gotten significantly cooler outside in the past few days.
Yep. My house is currently under invasion from spiders, they seem especially attracted to the warmth of my computer monitor. Last year when it got cold, many houses reported huge invasions of ladybugs (I saw an affected house, it was really gross). This happens every fall.
Same here.
You know, Chas E., Goddamn you for telling me that. 
I have been effectively reduced to an hyper-paranoid twitching nutcase in the past five minutes all for what? Fighting ignorance? HAH! My toe has twitched twice in the past two minutes(psychosematic no doubt) launching my knees into the underside of the table and waking up the entire house with my shrieks. Ignorance is bliis in this case.
I guess it’s my own damn fault; If I weren’t so damn supersticious I wouldn’t be so reluctant to kill a spider in my home(seven years bad luck!!! SEVEN YEARS!).
