When Do Avocados Turn Into Guacamole?

Whenever I bring avocados home from the store, I swear Shawn will just stare at them on the counter waiting for them to magically turn into......

GUACAMOLE!

I know for a fact he does not know how to get it out of the shell - I've seen him try...and it was messy. I guess it's going on my list of things to teach Shawn how to cook. HA!
