A natural misunderstanding

This is a story relevant to this blog about the effect of common ground, or lack thereof, on phonological processing and context driven disambiguation.

When my grandmother asked me why my brother wasn't at dinner, we had this exchange.

Me: Well, I think he's probably taking it easy at home, kicking back, looking at some blogs.

Grandmom: You're fresh alright!

Me: What? Why?

Grandmom: I guess it's a natural thing for him to do. Don't you look at the blonds?
