Imagine Sam and Dean drunk:
I was walking back to the hotel room, with food. We had just let a case go and the thing killed two more people and we didn't catch it, and it wouldn't be back out for another 6 years.
I opened the door and saw Sam sitting in a chair slumped over and Dean laying on the bed, both having a bottle of whiskey in there hands. "What!?!" I asked shocked. I quickly set down the food and grabbed the bottles. "What are you two doing" I asked and they shrugged. "Get up and come eat your food, I'm gone for what, 20 minutes and your both drunk." I huffed and got out there food.
"Your bossy" Sam slurred "what?" I asked. "Your bossy, and short" he said and laughed. I looked over at Dean and he was asleep. "Ok Sam, time to go to bed" I said and helped him off the chair. He nodded and I laid him in bed and covered him up. "Thanks" he mumbled and I covered Dean and ate my food.
