A relationship may be going along quite well, when suddenly a casual
conversation could turn into a bitter debate. If you choose to engage in this
debate, it could easily descend into an argument, so be prepared. If this is
something you really want to hash out, then be realistic about dealing with
the consequences. If you don't find a way to agree or to at least compromise,
you could create a rift that will last a long time. Before you do that, make
sure it's worth it; it may not be.
