Legal challenges

I'm not having quite so much fun this week. Although business is booming, we're having a dispute. We came to an agreement a couple of weeks ago with a potential business partner. Within a few days we realized that we had made a serious mistake and we tried to back out. We immediately received a long letter from their attorney. Now our attorney is involved and it's lawyer versus lawyer. Just the fact that this ended up in the hands of our lawyers so quickly indicates to me that this is a business relationship I want to end as soon as possible. However, we didn't realize the problem immediately and so it's going to take some time, effort, and money to extract ourselves from the situation (if it's possible). Ugh, ugh, ugh.
