I love relationship RP. I love 1x1. I would love to be able to slow burn relationships; lovers, master/apprentice, vampire/thrall, whatever. But we're living in the real world and it gets in the way. Allow me to awkwardly explain.
I've had terrible luck over the years. Disappearing partners, dead and dying games, time zone differences, player groups disbanding, my partners getting banned (That's happened about three times now. I need to be a better judge of character).
If I want to play out a relationship, I feel the need to get to the point and fast before everything falls apart. Instead, I try to play off the speed in which the relationship manifests. So there are misunderstandings, miscommunication and mistakes that come with fools rushing in.
Example: My thrall, early in his relationship with his vampire told someone (a fellow occultist and close friend NPC) about her. Not in great detail, just saying he had met a vampire and OMG he was SOOOOOO in love. (Stupid vinculum). This was expressed clearly as a no-no. Once. He misunderstood what was off limits and got a little too excited.
When he offhandedly mentioned that his buddy was concerned about him being with a vampire, He didn't realize he fucked up big time. Dumbass thought the concern was precious and he just had to share. Needless to say, vampire was pissed. It made for a great scene filled with rage and angst and tension.
Point is, I'm a carpe diem kind of player, because I never know when everything will just go boom and I'll be left holding the ball.
