I had a good JW youth. Got baptized when I was 14. Never had any problems with not celebrating holidays, did some occasional 'witnessing' to my school mates. I had a lot of friends at school and they loved to discuss religious matters with me. I laughed at them and they at me, and we mutually respected each other.
The only thing I regret: there was this one girl I fell in love with when I was 17, and she with me. I really should have uhm... 'explored' our relation a lot more.
