I just wanted to add... It turns out that I have a fascination with categorizing people. It's inherently interesting, plus it helps me understand people and improve my relationship with them. As long as any category isn't used as an ego trip, I'm all for putting labels on who people are, for that understanding, as long as the labels are flexible enough that they can change as the person changes or as a better category is found. I've found labeling personality- or soul-wise to be a good, but not perfect, indication as to who will have my interests and values. I would enjoy having Infant and Baby souls posting here since I'd like their take on spiritual and psychological matters.
Dave, French vanilla ice cream would go a long way toward bumping me to Old Soul, and even to full enlightenment if the supply is endless.
