Scratching at beard: "I love it when a plan comes together."
Hands swinging free: "This is a low-pressure shopping experience; I'm just browsing, basically, and sales staff attempts to assist will be rebuffed genially and with self-depreciating humor."
Pulling on ear: "So I've blown a wad and put in hours of work on an idea that, I'm learning now, is totally untenable."
Fingers making the shape of a square frame: "You may think that I'm pretending to make a film, but I'm not; rather, I'm contrasting the size of this coffin-sized safe with the height and width of my garage, which I'm incrementally transforming into a personal secret lair."

Wringing hands: "How can I overcome the logistical and gravitational roadblocks this project presents without convincing this Lowe's salesperson that I'm crackers and/or winding up divorced?"
Crossed arms: "I'm a motherfucking general contractor, and I am not impressed" or "Ace Hardware has a better selection of bathtubs."
Hands in pockets: "I wish I was anywhere else but here. Anywhere."
