The document discusses how the author brought Fresca to a party instead of beer even though the invitation said to bring your own beverage (BYOB). When the author arrived with the Fresca, people had a range of reactions from confusion and annoyance to finding it hilarious. By the end of the night, the author had become known as "the girl who brought the Fresca" and felt like they were briefly the life of the party, owing it all to the refreshing beverage.
