Summarize this article:

Then, whip out a small game console, such as a DS, DSi, 3DS, DS Lite, PSP, PS Vita, the Wii U Gamepad, Nintendo Switch,  or any other small device you may have. Make sure to keep the volume low if you're in a small house or your parents are just light sleepers. If you don't have a small game console, watch TV. If you can't watch TV, read a book. Do anything you can to try to stay awake! Use an iPod, MP3 Player, or another music device, with headphones. Wait for about an hour after your parents go to bed, to be safe. If you can, try to keep one ear free so you can hear your parents if they get up. If none are available, listen to it at a low volume. Be careful! Don't wake up your parent(s)! Make sure to have a plan if they wake up to check on you or something like that, like stuff everything under a pillow or your sheets. Observe how you sleep and try to look like how you "normally" sleep. Wait a couple of minutes till you take out your devices or music just in case they come back.

Summary:
Wait for your parents to go to bed. Listen to some music.
