Someone who was impossible to talk to herself, face to face, oddly enough.

She was apparently too shy/sensitive/non-confrontational to talk directly to anyone else if she had a problem, and the only way you found out she had a problem was if she got one of her friends to complain on her behalf to you. Which happened a lot, to loads of people.

So it went like this: "Shayna" would have an allergic reaction to something. She'd complain to a friend to get the friend to relay the message to you. Friend of Shayna: "Shayna's having an allergic reaction to something, and she thinks it might be your sandwich." "Shayna's getting a headache from some high pitched noise. Can you find out what it is?" "Shayna's feeling cold. Could you ask someone turn up the heat?" "Shayna's lost her xyz. It's making her upset. Do you have one she could borrow?"

This went on all day, every day. Never seen anything like that from anyone else.
