12 jurors or is that 13?

The 12 of us jurors are sent out to this very cold, bare room to decide who is to be foreman. Having learnt from before, I wait for someone else to start talking. One of us introduces himself and the rest follow.. then wait...most of us have been on juries before, nobody wants to be pushy, we will be together for weeks. A young bloke volunteers and we agree happily. Then one young woman says that she has a placement due in the next couple of weeks, if she doesn't go her graduation will be postponed for 6 months. Several of us say she must ask the judge if she can be excused, it is unreasonable for her life to be on hold for so long. We all troop back into the courtroom and she talks to the judge briefly, he does excuse her. Fortunately the remainder of the jury pool is still there. Another juror is balloted and because we are technically a new jury we go back to the little room, confirm our choice of foreman and return to the courtroom. We are then dismissed for the rest of the day and the next, unit a more modern and comfortable courtroom is available.
