Find out where that music is coming from.

Resolving to get to the bottom of this, you start walking directly toward your mom's room; the source of those crass beats. As you enter the hallway you could swear you smell marijuana coming from somewhere. You would never do something so gross, and you can't imagine your parents smoking. You resolve that it must be your neighbors smoking dope, but repress the urge to call the cops on them, since that would only bring down your birthday even more.

As you reach the end of the hall, you stand in front of your parent's bedroom. A set of wide wooden double doors muffles but does not block out the sound of people laughing and talking inside.

Male people. And a woman's voice which sounds familiar, but you don't recognize at the moment. As you register these facts, you hear a toilet flush from behind the bathroom door across the hall. The sink then comes on.
