He’s excited to start classes and enjoy the college party scene. Friday night, everyone gets together before the parties. Some students choose to drink before going out. Tim has never drank before. He decides to give it a try, but he remembers to turn on his phone’s DrinkDoctor application! Everyone’s in a hurry to go party, so they drink very fast. Tim has the equivalent of 5 drinks in just 15 minutes. James asks Tim to have another drink, but DrinkDoctor reminds Tim he may not feel the alcohol’s full effect yet. He decides to pass. Tim goes out to the parties, has a great time, and returns to his dorm safely. Tim has really enjoyed his first Friday night at college.
