House Rules-Discussion

How do we want to handle the extension of one's Parma in this saga?

I started a thread about this topic some time ago and there didn't really seem to be a conscensus on how that works. It seemed to range from:

Just touch the person for a few moments (a round) and if they are unresisting that constitutes consent.
to:
You must reperform you Parma ritual (2 minutes) in the presence of the person you want to share it with, who also must have made his consent explicit.

I personally lean more towards the first than the second, but it might be good for us to decide which side makes for the best stories in this saga. What is you opinion?

(I'm not looking to rehash all the arguments put forward in that other thread. Rather, I simply want to get a feeling of what each player feel would be appropriate.)
