Well, it depends who asks you. If the person looks worried when asking this, you may leave to be understood that you started something by your own and it would be great if the person would be willing to involve in this too, to help you. If she agrees, then you should give some more details about SFI.
If you have to deal with an ironic person, well, then ...maybe you would say you do not care about this very much because God will help you for sure.
