someday...

The younger lad is just embarking on his Kindergarten year, but he and his older brother are already thinking about college:

elder lad: "When I'm in my third year of college, [my brother] will be in his first year... so we could be roommates."

younger lad: "yeah!!"

elder lad: "I'd get my own *crunchy* peanut butter."  (Some things never change, but I've never known him to opt for crunchy peanut butter over creamy; college does crazy things to some people.)

younger lad: "yeah!!"  (He doesn't even like peanut butter.  no matter.)

elder lad: "AND let's get salmon and tomatoes for sandwiches."

[?!]

younger lad: "yeah!!  and we'll make baking soda and vinegar volcanoes!!"

Nefarious plans for those volcanoes and other pranks of increasing shock-value follow as their conversation gets more and more excited.  Downstairs neighbors of these two characters, be forewarned...
