I have always heard that people who are Jehovah Witness do not celebrate holidays or their birthday. I'm curious to find out why? Also, what do they do when there is a national holiday? Treat it just like a day off...? Finally, I have also heard that Jehovah Witnesses do not socialize with people who are not Jehovah Witnesses. Is this true? Would you attend an event, house party, wedding, etc...that non Witnesses are hosting?
