The Whyville Help Center is a bit different from most Whyville chat screens:
Here, you cannot whisper or chat freely.
You can only hear what the Helper says, or what someone in the chair next to the desk says.
The Helper can hear you even if you're not in the chair. If you have a question, you can let him know and he'll call on you, in order, to sit in the chair next to the desk.
