I love knowing other people's secrets
Oh really now? Do you also want to know what I think?
Yes, I want to know everything
It is ok you know other people secrets. If you tell other people secrets people will be reluctant to tell you any more.
I know, this is disappointing.
It may be, but if you keep all their secrets to yourself I'm sure people won't mind! They would see you as trustworthy person and would love to confide with you.
