Mating no less. On the windows we looked through just two days ago at a cute little baby robin entertaining our cat.
Unfortunately, I am the screaming arachnophobe girl and will only kill a spider if I have to when it is in my house and I can't holler at someone else to do it or use my vacuum cleaner hose attachment to suck it up.
Which means that we will have more spiders running around due to this uncensored window activity in the near future.
I do not like them this close to my door.
It was a free and unnecessary homeschooling lesson.
