Hell yeah! I imagine if people in the Forgotten Realms universe were celebrate Halloween, most would be too afraid of the drows to dress up as them, but a lot of children (and perhaps adults) would dress up as tieflings. They're just too calm when they meet drow who have a very bad reputation after all, and even if there are good drow communities, most people probably only associate dark elves with the cruel followers of Lolth. It has always touched me as I read Drizzt's adventures how Drizzt has had to contend with the distrust and hostility of other races for being a drow. This created an amazing atmosphere, reminding that Drizzt was not a human, or even an ordinary surface elf, but a dark elf who had grown up in a society of cruel creatures with a terrible reputation. I'd love to experience something like that while playing, both as Lolth-Sworn Drow and Seladrine Drow. And maybe a little less, but still, I'd like to experience a similarly negative reaction as a half-drow.
