bad humour + good story (hopefully)

nightmare thinks about helping dust

"Dream"
"Hm?"
"Uh..." i fiddled with the spoon that was in my now empty coffee mug, "...Dust isn't doing very well, how do you think i should help?"
"Well, what's wrong? why is he upset?"
"I heard Blue in his room-"
"BLUE WAS HERE?" he suddenly exclaimed

 
"Yes, he's like his therapist, do understand" i say, " He obviously thinks he's sneaky and that i wouldn't know but i do"
"Nightmare he's supposed to stay home!"
"Don't tell me!"
"Anyways, what did you overhear"
"Not much, i was passing by thats all"

"..."
"Maybe his hallucinations are back?"
"Good point"
"So how do i go about being nice?"
"Its not rocket science...just ask him about it"

"Ask Dust how he feels...yes...perfect...if that is how you want to die"
"Killer why are you here?"
"Mhelp"
"We can do this ourselves" i say
"Yeah, considering you know him so much don't cha now?" he says, looking at Dream, grinning like Chuck-E Cheese

"..."
"Well, how would YOU go about solving this?" Dream says
"Call Blue over again, get him to talk to you with Dust's permission of course..."
"Then?"
"Then just use that information to uh...erase all depression i guess"
"Killer you can go" i say, interrupting them
"Alright, but i warned ya" he says, leaving as he winks at me
Why is winking at me?
What is that supposed to mean?

"Dream"
"Yes?"
"What does winking at someone signify?"
"Ah...i actually have no clue"
