I let the boyz go downstairs and check out the progress on the basement. Diego-san inspected every inch, and made some auditory noises I've never heard him make before. It almost sounded like an "ahhh" and an "Ohhh" as if he was impressed by the framing work or the layout of the space.
Theo was reluctant to come all the way down the stairs. He kinda stood at the top and sniffed around. Eventually he joined Thompson and Diego in walking around. When I finally made the boyz go back upstairs and shut the door to the basement Theo was the one who stood outside the door and whined away- wanting to continue to check out this new part of his world.
