Implications of talking by fireplace

Since the WW doesn't have "fellytones" and seems to be in contact by 
fireplace/floo powder, how would you contact friends just for a chat?
Their 
teenagers are so deprived! ;-) Imagine it: evening in a wizard
household. 
"Ron, get your head out of that fireplace, you've been on for two
hours now 
and I'm waiting for an important floo from the MoM! No, I don't
*care* if you're 
talking to Harry about the party!" It wouldn't happen, of course -
it's way too 
uncomfortable to be kneeling in the fireplace, as Harry finds in OoP.

Or would they just send owls back and forth? Not very practical for
the 
average householder, like the Weasleys, say, with only one little owl
(Pig) and 
one elderly owl (Errol)... And no fun, either.

Sue, in a fit of whimsy.
