Bugs vs Bugs

Here is a copy of the conversation I had with Kelsi today on our walk to school

Me: Stop touching Tory's face, Kelsi we have asked you not to.
Kelsi: Why?
Me: Because you'll give her a bug and I dont want her sick
----Long Pause----
Kelsi: Mom can ladybugs make you sick?
Me: (Confused) What?
Kelsi: You know you said that if I caught a bug I would be sick.
Me: Oh, (laughing) No I meant a virus
Kelsi: So ladybugs dont make me sick
Me: Nope
