To what event does Adam invite Amal in Chapter 27 and what lie does she tell to get her mother Jamila to let her attend?

Adam tells Amal at the bus stop one day that he wants her to come to his birthday party on Friday night at his house. Amal hurries home to ask her mother Jamila if she may attend the party. She is honest about many different aspects of the party, telling her mother that she is not sure if Adam's parents plan to be there or not, for example. But when Jamila asks if there will be alcohol at the party, Amal lies to her mother, saying that there will not be any alcohol, when she knows full well that there is always alcohol at these types of parties.
