Fingernail polish

A boy asked a girl in a Star Wars shirt what her life was like. 

She told him "it's like my fingernails". 

Questioning her answer he said "what a strange answer"

She replied "what a strange question"

Curiosity itching at him he asked her to further explain the answer she gave but 

she simply told him to try to himself. So as they sat waiting for their planes to start boarding he guessed a list,

-typical?

-chipping away or unfinished? 

-messy as heck (he didn't say heck) 

-unpredictable?

-opinionated?

-colorful?

Before she could say anything they announced boarding had started and she began to walk over. The boy was beginning to get frustrated and rushed after her. 

"Wait you can't just leave without telling me what you meant" 

Shrugging her shoulders she said "it's a mystery I guess"
