Summarize the following:
Avoid arousing suspicions around bedtime; just do everything normally, such as teeth cleaning and saying goodnight to everyone in the house. If you know your parents will check on you before going to bed, listen for when they come. Hide whatever you are doing and pretend to be asleep. Normally, when pretending to be asleep, you do not move, however, it is okay to turn a little in your "sleep". Don't snore unless you are known to snore. It helps to pull your blanket over your face to save half the trouble of keeping a straight relaxed face. Consider sleeping with the radio on to give you cover. If you accidentally make a sudden noise, it'll be blamed on the radio.
Follow your usual bedtime routine. Prepare for the bed check.
