I don't know if this means so much to anyone but I grew up with my family being members of the Kingdom Hall. SO celebrating holidays was a no-no and of course any child feels isolated when not attending classroom parties or even holidays, that is if the reasonings aren't explained real well.
Holidays are rooted in pagan beliefs and anyone can see that. Halloween being the day where you dress up to ward off the ghosts and goblins that get the 31st to roam around. If you ask yourself anything, do you want your child participating in something that deals with the devil however direct or indirect it may be? One little boy told my 11 year old that since she didn't celebrate halloween that she didn't believe in God. Crazy. Another holiday is Christmas. Which to me if it was a day for celebrating Christ's birth, where is it stated in the bible that december was the month or even the date pointed out to be considered holy? Why do people feel the joy and love on his birth-day but yet give "others" gifts? To me if true christains was to honor, not celebrate, his birth it would be in a spiritual manner. Yet it isn't his birth that meant the most but the fact he died for our sins which is not so nationally observed.
