"Don't press it hard, just put your thumb on it— damn it!"

The call times out and drops again before Iroh gets the chance. And Zuko calls again, grumbling to himself as he does. Before his call comes through again, Iroh will see a notification about his multiple missed calls pop up on his screen... Zuko's not coming in until they demonstrate this the way he wants to. His vision is fixed. He will continue to yell through this door like the bratty child he is — or at least, can often be... He means so well, though, he really does, just work with him here, Iroh!!!
