Training/Firing a misbehaving client

Dear $CLIENT, I understand your frustration. I really want to help you build the app you want. I was hoping we could speak openly and clarify some of the expectations on both sides. $TASK is what we initially agreed upon and I'm fully committed to delivering that. As you'll recall, $CHANGE isn't a part of what we discussed. I know that $CHANGE may seem simple. Sometimes seemingly trivial changes affect the development in surprising ways. I understand that you have needs for your web project and I want to do my best to help achieve your goals, but please understand that I need to be clear about expectations in order to help you effectively. If you feel this is no longer a fit, we can agree to part ways and move on amicably. Otherwise, let's discuss how we can move forward together and achieve your business objectives. How about a quick 15 minute phone call at $TIME this week to discuss and realign our goals? XOXO, ezl
