Psychological Disorder Number 4868:
I always use exactly 3 dots for ellipses (...). Aside from the fact that this is the grammatically correct form of ellipses (which really is a good enough reason all on its own), there is a deeper psychological oddity at play, namely Ex-Boyfriend Defiance Syndrome. Ryan always did ellipses with only two dots (like this..) because he thought any more than that was overkill.
I am a mental case... :D
