|Deeply absorbed in thought.|
As distant and bemused as a professor listening to the prattling of his freshman class.
Lost in thought.
A preoccupied frown.
|Perplexed by many conflicting situations or statements; filled with bewilderment.|
Obviously bemused by his questions.
Bewildered and confused.
A cloudy and confounded philosopher.
Just a mixed-up kid.
She felt lost on the first day of school.
