Even in the wizarding world, hearing voices isn't a good sign

I am trying to read.
I'm looking at the page and trying to concentrate.
And then it hits me, that the reason this table is the only one free in the Employment Resource Centre is because of the woman at the next table.
She is having a very motivational discussion, full of "I'm the only one" and " no one else" and some muttering I can't hear clearly. She can obviously hear ALL the voices.
I look up from the paragraph I've read twice already to see her grining at me and saying 'hello' like we are long lost friends.
I say a very quick 'hi' and go back to my paragraph and she goes to chat to the photocopier.
I myself have had many chats with photocopiers, usually along the lines of - 'what the hell are you doing? I didn't want that' or 'ouch, that hurt'.
I couldn't quite make out what she was saying to the photocopier, but it was being much nicer to her than it ever has to me, so that's it! I'm never speaking to it again.
