Welcome to JWN and thanks for posting your story.
I was not raised in the "truth" but there was always one or two witness kids in school who did not sign a birthday card or participate in holidays. I never made fun of them; I respected their beliefs. Later in life I became a witness. Then thru Classmates.com and other sites I got in touch with those former classmates to let them know I was now their brother....but to my surprise every single one of them said the same thing you did. They said throughout their childhood they "went thru the motions" because their parents forced them, then as soon as they graduated and left home they left the organization. I was shocked. But now once again I am on the same team with them.
