you never know when someone from your past is going to pop back up Very true. In some cases, you may be the one to pop back up. I left my old company in part because I was brought on specifically to work on a number of projects that were later shelved because of the economic downturn. I eventually left to pursue them on my own, and they may be interested in buying the finished product. That possibility would be off the table if I had written a nasty letter when I left.
