How hard it must be: being left alone in the middle of a speech, a program in progress. All at once your resources are estimated scarce, not enough or far from the upcoming fashion. So you soon get forgotten. No one knows whom you belong to, how and why you got there. Therefore, no one will ever pretend you again, the many ways you could still be helpful to them fall into oblivion, the program you were promised is lost or replanned.
The speech diverts and get far from you. So much that you can't anymore understand and everything gets blurred and indistinct. You must shout out loud to make yourself heard and wanted again.
