Mr. Chair, I wish I had known before, because I have other appointments.
As the extension of the meeting wasn't planned, we weren't able to prepare for it. Had we known in advance, we would have prepared our questions. However, we have other things to do. I'm sorry about that.
The meeting went well, but we should have known about the extension. That way, we could have found people to replace us, which isn't currently the case.
