Me: (standing in the living room) Has the boiler always been this loud?
Zoo: Yes. Because you’re standing right above it.
Me: I’ve never heard it this loud. (goes to basement, opens door and hears weird click clack noise.) I’ve never heard that noise before.
Zoo: I’ve heard it – it’s running three zones at once.
Me: One zone is running. One. You’ve really heard this noise before? Because, like 13 years here and I’ve never heard it.
Zoo: I’ve heard it before.
Me: Before this morning?
