Castiel stares blankly at the device in his hands. "What is this?" He asks quietly as he turns it over. Dean sighs and takes it from him, flipping it open.
"A cell phone, Cas, helps you keep in touch." Castiel tips his head, his signature move to show confusion,
"I do not understand..." Dean wants to smile at the angel's lack of knowledge. Instead he sighs again and hands the now open phone back to him.
"Look, just hold down the one button when you need to talk to us and we aren't around. We'll get you some more minutes when you run out, okay?" Castiel blinks several times, looking as bewildered as before. No, he didn't understand. Dean understood this, but left it as it was. "When I call you, you open it up and hold it to your ear, okay? Easy."
Castiel pretends to understand and nods once, snapping the phone shut. Dean gave him something, he'll obviously take care of it. "Thank-"
"Shut up, featherbutt. I know you don't get it. Man, you're so easy to read sometimes."
A small pout crosses Cas' face for a second before tightening into a frown, "I AM trying, Dean. You humans are hard to understand." This brings a smile to Dean's lips.
"I know, don't sweat it."
"One cannot "sweat" this kind of thing, Dean..."
