I think I just got bitten by a spider! What do I do?
user
Oh no!  When you say bitten, what do you mean?  Did you see the spider?  Was it a dangerous kind?
assistant
I did see it! It was black, with a red stripe on its back!
user
Hm, you’re describing a black widow spider.  But I’m not sure what “bitten” actually means, does it feel like a sting?  Is there a bump?
assistant
It hurts alot!
user
Oh gosh, is there a red bump or swelling?  It might be an emergency!

Okay, I’m not sure what you’re feeling.  Are you still seeing the spider?  Can you describe the spider and where you found it, and also describe how it got on your body?  Also, what did you notice immediately after it got on you?
