premise: On one such evening last October , Elena slid her assignment sheet on the table in front of me , purposely lingering her neatly manicured hand for a few seconds to make sure I noticed the U.S. flag design she had placed neatly on each nail . A little overdone , but cute - in an " in - your - face " kind of way . I chuckled . Why did Elena do this in front of me ?
hypothesis: She wanted to flirt with me and show me her good hygiene .
