I really think this depends on the people involved and their dynamic. Are the friends people who see each other from time to time at events, but don't really enjoy things one on one often or at all? Are the friends actually quite close?
Useful questions I did not think of. In my case, a friendly acquaintance who I have enjoyed hanging out with alone & we don't get to do it that often. I like the person enough that I would like to stay "friends" and not extinguish the possibility we could become genuine friends if were able to hang out more.
I've enjoyed playtime with acquaintances and closer friends. The only reason I agreed to do so was because we communicated well. We've been able to discuss ideas, limits, and discuss if something is not working. There has to be a line drawn between fantasy and reality. I also have to know the friend I'm considering playing with has a firm grasp of this as well. [/quote]
Insightful. I agree, both people would have to understand the need for the different boxes, not everyone can communicate that way. OTOH, someone who could communicat like that ( very frank, deeply personal ) would be enthused to make better friends with regardless.
