"Sophie, what are you spacing out for?" Her classmate from London, who worked with her at the restaurant, walked over to Sophie and patted her on the shoulder.
Snapping out of her thoughts, Sophie forced a smile at her colleague and said, "It's nothing, I just didn't sleep well last night. I'm not feeling very energetic today." Then she put her phone back in her pocket.
"Oh, same here. My sleep quality hasn't been great lately either. Could it be nervous exhaustion?" The colleague suddenly remembered something and asked, "Didn't you say before that you were planning to transfer schools? Before you transfer, are you going back to London for a visit?"
Sophie shook her head.
