Looking at timing:

• It takes 38 frames for Emma to walk into frame with 18 frames for the body weight to follow through.
• Pauses and slight actions are sometimes more important than larger actions as the awkward pause between the two characters takes 111 frames and Katie's sarcastic wave takes 48 frames.
• Down movements are quicker than up as Emma puts the box down in 27 frames but stands up in 59 frames.
• Katie turns - 35 frames
• Katie's lifts box - 44 frames
• Katie up ladder - 297 frames
• Box on shelf - 75 frames
• Pause - 77 frames
• Down ladder - 94 frames
• Jump (including follow through action) 38 frames
