Castiel had been with the Winchesters for a few weeks now, and during that time they had tried to provide him with as many opportunities as possible to learn normal human behavior before they let him out of the bunker. And although he could brush his teeth without wasting the entire tube now, he still managed to struggle with most other 'normal' things. For instance, how to use a shower. That problem had Castiel staring for over an hour at the running tap, before Dean had to step in and help him. And then tell him,"Cas, buddy. You can't shower in your clothes man." That was one of Castiel's worst problems, actually, at least in Dean's eyes. He never seemed to know what to wear when, or even when to wear anything at all. Now was one of those times.
Sorry for this being so short, it's just the beginning I promise! It's more of a prompt for me I guess, to actually start the story. I hope it's okay, and please don't be too harsh if you decide to review, because it's my first time actually writing something like this. Thanks!
