* Subject: You
* Verb: walk
Let's explain why:
* Subject: The subject is the person or thing performing the action. In this case, "you" is the one doing the walking.
* Verb: The verb describes the action being done. "Walk" is the action the subject is performing.
The words "hesitantly," "over," "to him," "with," and "an uncomfortable smile" are all modifiers that describe how, where, and why the subject is walking.
