"Are you getting tired, Jennifer? I saw more of a struggle when you put up these glasses"
"A bit cold again, but not really tired. What you just told me about the Haarlem script keeps running through my mind. But I am really motivated to go on"
"Shall we take a break?"
"Not yet. I'd like to go on for a few minutes. Tell me if I look more tired in the next pair of glasses"
"That's common sense, Jennifer. We will do as you suggest. How about one more picture?"
