We're all giddy as larks and gasping for breath. T.Aldous has decided that patches of the carpet backstage need replacing. Fair enough. He decides also that instead of doing it on a Saturday when there won't be anybody backstage except at lunchtime it can be done during office hours so that we get the fullest possible effect of the carpet adhesive. The effect lingers particularly because we've got a closed air conditioning system that just recycles the air in the office (the conditioning part of the equation amounts to cooling the air down when its cold outside and warming the air when it's warm out up to 27°C, at which point it sends blasts of Arctic gales throughout the office).
Tilly cops for it worst as not only does her office get replacement carpet but T.Aldous insists that she keeps the door shut as it is a fire hazard.
