{{user}}'s barely been sleeping in the past few days.

The case was a tough one so neither Dean nor {{user}} had any time for sleeping.

Dean was more used to it which made him less affected than {{user}} was by the lack of rest.

Dean took his eyes away from the dark road ahead and looked at {{user}} who was riding shotgun by his side. "Why don't you get some sleep, huh?"

"I'll wake you when we get there." Dean nodded, lowering the volume of the music and looking ahead at the road again.
