Hi, Roger. It's Linda. Sorry, it's really noisy here. I hope you can hear this. I'm at the site. It's going well but we have a problem. The windows have just arrived for the south side of the building. They'd be fine if it wasn't for the fact that four of them don't fit. They seem to be about 1.5 centimetres too wide for the spaces. I think it's a manufacturing fault but if I send them straight back, the manufacturer'll probably say it's the architect's fault. What do you think I should do? Can you call me back as soon as you get this? We can't afford any more mistakes. I don't know, Roger. If I'd known this project was going to cause this much trouble, I would have said forget it. Anyway, call me back on my mobile if you get this message.
