Worst case scenario: You step back in the house at 4am and your parents are both awake, sitting up and looking angry. What are you going to say? Some possibilities:  "Steve called because he needed to be picked up from a party and was really upset. He's going through some stuff. I didn't want to wake you guys up, but I just wanted to do the right thing. Sorry." "I couldn't sleep, so I texted Amy and we just took a walk around the neighborhood and got to talking. She's kind of upset, so I didn't feel like I could ditch her. I think I'm going to make some warm milk. I'm exhausted." "It's such a nice night, I went out to look at the stars. Guess I fell asleep." Alternatively, you could just own up to it and take your licks: "I met up with some friends. We just hung out for a while. I'm sorry. I won't do it again." Avoid stupid excuses like, "I don't know what happened, I just woke up here!" Far-fetched excuses won't get you anywhere. Your parents are not dumb. What if you get to the meeting place and nobody is there? What if you end up walking several miles and need picked up after getting ditched? What if you get picked up by the cops for a broken curfew? These aren't things meant to scare you, but you need to think ahead of time about what you might do if you end up in a tight spot because you're better safe than sorry. That way, you'll be able to relax and have fun. Do you have older cousins to call, or could you get away with calling a friend's parents? Think about your options and clear it with them ahead of time. Let them know you might need them before you find yourself outside and in need of a favor. If your parents get suspicious and want to check up on what you did last night, make sure that according to your phone you were in bed when they thought you were. Delete relevant texts, photos, and other information that might incriminate your night out. Don't text about it, don't tweet about it, don't update your social media accounts with, "Snuck out last night!!1!" Mum's the word. Once you're in and safe, make sure you straighten everything to basically the same place where it originally was. Especially if your parents are very tidy people, you'll want to make sure you don't leave your shoes or keys in a conspicuous place where they'll notice them. If you spend all night cavorting around, it might raise suspicion if you need to sleep until 2 in the afternoon. Set your alarm for the late-side of a regular wake-up time and try to get as much sleep as possible. Take a nap later in the day to catch up if you must.
استعد بحجة غياب. فكّر في أسوأ السيناريوهات المحتملة. تخلص من الأدلة. أعِد كل الأغراض إلى موضعها. انهض في الصباح وكأنه يومٌ معتاد.
