Vacuous is a term used to describe a person who has void or desire that needs to be filled. This person is looking for something. Often times, he/she might not now what it is, how they will find it, or where it might be. The desire to fill this void is often very strong. Frequently, more than one thing is required. Wanting to fill this void does not make you selfish, or blackhearted, despite what some might say. Being vacuous makes you determined and ambitious.
Albert is vacuous and hopes he knows what he is looking for, even if it scares the shit out of him! He just has to be patient and understanding.
