Are you good at keeping secrets?
I haven't had the opportunity, so who knows!
Have you ever let slip a secret a best friend swore that you must keep?
See above
Has a secret that you've told your best friend ever been slipped out?
Eh...I didn't tell her it was supposed to be secret, I just assumed she would understand. It wasn't really a big deal, though.
Do you carry a big secret right now?
Not that big I don't think xD
