Sometimes the words 'dialogue' and 'communication' are used interchangeably, but they aren't the same. Dialogue is a type of communication, but communication isn't necessarily dialogue, because dialogue implies a certain reciprocal respect, a certain bilateralism.
To put it another way: a screaming fight with someone isn't dialogue, though it might enable both participants to communicate how they feel. Dialogue, or at least amongst the womens' studies set, is about talking with someone and having both speakers get something out of it. It's supposed to be productive.
Today's video of part of a recent live set by Trophy wife opens with a song about this very topic. Enjoy, and maybe reflect on your communication skills, on this hump...night. I know that's what I'll be doing.
