More of "getting down with the sickness"

What goes through a person's mind?

I was visiting a friend over the weekend and his mother came in.
She served us some pate and rum balls.
All food that requires a lot of handling to make.

After I ate everything she tells us about how she's been suffering with the world's worst cold ever. She says this right after she handled my food. Why not toss some arsenic in it for good measure to really be sure I get sick?

What are people thinking?
