MEMORY SHARE MEME
That says memory share, not memeory share. Anyway, the gist is this: characters get a chance to share memories with another one. It can either be voluntary or involuntary (on both characters' parts. maybe discuss non-consensual telepathy and shit ooc first). Mind melds, pensieves, jamjar situations forcing it on everyone, whatever. Sometimes you experience the memory like it's happening to you or sometimes you experience it as though spectating it. Sometimes you get to choose which memory and sometimes you don't. It all depends. Maybe it changes your relationship forever, maybe it catches you out in a lie. In any case, now you know something about each other you probably won't ever forget.
