Exactly. One of my favorite things about my L5R group was the fact that my super-honorable Lion had to pal around with another player's Scorpion who was constantly making my character's life more difficult (even if my character didn't know it). It takes player buy-in to the style, even if unspoken, but it can be a lot of fun.
Hell, several of my friends had a tendency to make characters (in any particular game) that were adept at getting on my characters' nerves (note: always the characters not the players). That might just be our group dynamic coming through, though.
