Kid: Our neighbour’s painting his house with a half-inch brush and my da says it’ll take the contagious.
Yeah, yeah=yes
Yeah, yeah=I suppose, but I'm not thrilled about it
Yeah, no=no
No, yeah=yes
No, no=I'm sorry you misunderstood let me clarify
No, no=you don't have to do that I'll take care of it
