Not to sound rude, but why would you want to go to this made up event?
The entire event is a lie, it is based on make-believe doctrine, based on incorrect interpretation and the practice is neither consistent or enforced (re: 144,000). Why any logical sane person with reasonable deduction skills would want to sit and partake of this pseudo-spiritual celebration is beyond me, especially after they have "awakened". The only way I can see the possible justification of going is to support your wife. But don't you realize as long as JWs feel they have a shred of a string to control you or infer their will over you, they will pull on it like a noose? You have free will, use it. Just think about taking this as an opportunity to break free of this group-think and find your individuality.
