Are あなた good at keeping secrets?

Yes.

Eh, when I feel like it.

I'm afraid that's classified.

yup

Yes, but only because I have probably forgotten it within eight 分 of having it told to me...

I hold many.

I'm great at holding secret.I never told anyone my brother wore a tutu..............opps

Not really :/

Yes...I guess

Yes and no.
if it's a minor secret, i can keep it to myself and not even give hints that i may know something others don't.
However if someone has en-trusted me with a secret that i believe may harm some person/animal/themselves either physically, emotionally または mentally, then i will take the correct steps to intervene subtely, as well as go to the proper authorities to ask for アドバイス without giving names and most details unless absolutely nessacery.

why do あなた need to know? >:3
