Me and my dog spot have been arguing over which is the proper word to use when refering to myself and my other personaltys. I say "we" because its plural Spot says I should use "I" because I am one person. This argument has gone so far we are no longer on speaking terms Please give me your input.

we sounds the best in your case

Or "Me and (insert other personality's name here)"

it depends... is a person a physical being or is it a just the idea that a "person" exists?

per�son�al�i�ty

1. The quality or condition of being a person
   
2. The totality of qualities and traits, as of character or behavior, that are peculiar to a specific person.
   
3. The pattern of collective character, behavioral, temperamental, emotional, and mental traits of a person.
   

i vote for "I."

um, id say 'we' if ur refering to 2 different personalities, like scitzophrenia (sp). as in if u have two opposing thoughts kinda thing.

evil me:Split personalities don't exist, it's just excuse for being who you really are...
good me:No! they do exist...
evil me:Get a life loser, who needs inhibitions and excuses...Again they don't exist...
good me:argh! your wrong, split personalities do exist...
evil me:Sorry! be right back... gotta kill my obstruction... BANG! CRASH! Whhaaaaahhhhhhh!!!!!!!!!!!!!!!!!!!!!!!
good me:I win! And I guess now I stand corrected, split personalities don't exist...

^_^ sorry too many people here...

Just remember, Schitzophrenia is voices, hallucinations, and general insanity. Multiple Personality Disorder is multiple personalities.
