Annabelle's Worries

In one of the classroom of imperial university professor was writing something on the Blackboard while all the students were paying their attention towards him. In quite classroom where everyone was studying attentively one girl was sitting there dazed.

Her eyes were glued to the blackboard but nothing was sinking in her head as her thoughts were wondering somewhere else.

"What happened to you?" Ethan shooke Anna's hand. The class was over and everyone were leaving but the girl was still looking at the blackboard, spacing out.

As she sensed him shaking her hand she came to her senses.

"Hmm what... What happened?" Anna asked dazed.

"Class is over. It's time to go home." Ethan said as he pointed out at the leaving students. The class was almost empty.

Anna saw and realized she was so deep in her own thoughts that she didn't even realize that it was almost time to go home.
