One of the massive benefits of getting married in the first place is having someone else around the house to deal with all the hard jobs (read: remove spiders), as far as I’m concerned. No more trapping them under pots and running away. You can always rely on your guy-partner to do the work you don’t want to do.
Unless you’re married to this guy. Removing the spider was obviously far too much hassle, so the sign will have to do. Maybe you should just seal that room off for the rest of the week, but 52 weeks seems like a much more appropriate safety measure.
