Bertie: What's up with you?
Oliver: I've just discovered there is another thing I can't eat.
Bertie: Plastic?
Oliver: No, that's ok. I can eat that. It's Avocado.
Bertie: Green, mushy, goes with tacos?
Oliver: Yep, that's the one.
Bertie: What's wrong with it? Apart from the obvious, of course.
Oliver: It has something in it. Um...persin. It's a fatty acid. And it might make me have trouble breathing, or give me fluid on my chest, abdomen or heart.
Bertie: Eww.
Oliver: Or abdominal enlargement. Don't say it!
Bertie: My lips are sealed.
Oliver: So that's one more thing I can't eat. I'll have to dream about eating it, like I do about Chocolate, Grapes, Macadamia Nuts and Onions.
Bertie: And plastic.
Oliver: No, I told you, Plastic's ok.
Bertie: Yeah, sure it is, O' Delusional One.
