"That's a question for you,'' the Prime Minister replied.

Of course the (unspoken) answer was "yes'' because the national media isn't overly concerned about school funding arrangements in the ACT.

And the second school sandwich-throwing incident in a few weeks is an interesting change from the rock star treatment the PM usually receives when she visits a school.

Teachers had obviously carefully prepared a group of students to ask the PM questions in the library.

Their questions were written down and rehearsed. But unfortunately the PM had to walk down a corridor full of other students to get to the library.

As Gillard made her way through the crowd, shaking hands, a salami sandwich flew through the air and briefly made contact with her arm.

She laughed it off, as did Chief Minister Katy Gallagher.

Once she was safely in the library, Ms Gillard answered a question about new technology by talking about the days when as a lawyer she learnt how to use a fax machine.

The PM also talked about how she copes with the stresses of political life and public criticism. She said having the support of close friends helped.

"I think if you were unclear or filled with doubt about what you're trying to achieve you get buffeted around more easily,'' Ms Gillard said.

"But if you're very clear and very determined then it means you're more solid, even when negative things are being said.''

Compared to the verbal spears thrown at them almost every day, a sandwich was not even a minor irritation to the Prime Minister and the Chief Minister.
