Lyrael -
I answered your question on Meredith's thread but thought I'd post it here too.
I think there is a trend that people who express in acts of service seem to like to receive in words of affirmation. That makes some sense, because when you do something really nice for someone, don't you usually expect to hear "gee honey, that was really nice, what a great job, you're so talented"? So I think those of us who really need words of affirmation may gravitate towards acts of service expecting that words of affirmation will be our reward?
