Do you think your best friend is keeping a secret from you? Follow these steps, and get them to spill their guts!
[edit] Steps

1. Casually ask them if they have anything to tell you. Just during lunch or something. Like, " Is there anything you need to tell me? You seem kind of secretive." If they say no, no worries! This'll help you.
2. Later on, sit them down, just the two of you. Say something like "I noticed that you're acting kind of weird around me. Is there anything you need to tell me? I swear I won't tell!" Sometimes they'll tell you at this point, but if not, don't push.
3. If they still don't tell you, email them or text them and ask! At this point, if they don't tell you, you have two options:
4. You can back off. Leave them alone. If they don't want to tell you, they won't! Or you can:
5. Say "We're best friends. And best friends tell each other things," or something along that line. If they don't give in to that, then just don't talk to them for a few days, and in a few days, talk to them again like everything is normal.


[edit] Tips

* Keep in mind: If they want to tell you, they will. Don't push too hard. Do one step a day.
* Manipulate. I'm not saying too much, but just say something like "I thought best friends told each other everything." They probably will tell you at that point


[edit] Warnings

* They might get mad at you.
* They might not really have a secret.


[edit] Things You'll Need

* A friend with a juicy secret.
* The gift of manipulation.
* Patience.
