Selfish?

I wonder, is it completely selfish of me to wonder how events occuring in my life will effect the wedding? I'm talking events that have far greater pull in my life than solely on my wedding, but inadvertantly, make my life a living hell.

And is it selfish to wonder why the people involved can't look beyond themselves, to the people they're affecting?

Like, how will we work the parents' tables, if mine can't sit together?
