Dear Spider.....Dear Spider,
Welcome, my arachnid friend. I appreciate all the work you do. Without your help we'd have far too many insects buzzing around. Your dining habits make my habitat much more pleasant.
Your webs are lovely, but I'm sure you already know that. Even so, I am greatly impressed by your work. What an amazing thing to build without thumbs!
I do have one small request. I am not a fly, beetle, or mosquito. I'm a human. As such I am FAR too large for you to eat. I'll do my best to leave you be, so would you please refrain from biting me? You're small but that venom packs a punch!
With warm regards,
