Laggies (2014)

Megan's approaching 30 with a good degree and a boyfriend in hand, but when he proposes at her friend's wedding and everyone seems to think that the best way to advance in her career is to take a seminar where you find out what animal you are, Megan understandably feels lost. After meeting teenagers who want her to buy them beer, Megan is drawn into 16-year-old Annika's simpler life. She ends up moving in with Annika and her single father, juggling the life of a teen and that of an adult, two romantic interests, and the feeling of lagging behind.
