[Something visibly eases in Dave once he draws an ice pack out of the freezer. This is the world he knows. With the skill of practice, he wraps a towel around it and sets it on the table. He motions for John to take off his glasses again.] The thing they don't tell you is you shouldn't keep an ice or heat pack on for more than ten minutes. You're chilling or heating that area. Too long and it gets damaged.

Ten minutes on, ten minutes off.

[He presents the package to John as he adds.] Eat yet? Or have you been busy stalking a tiger all day and forgot to?
