You're right. But Patrick indicated to me that he was happy for me and that he would understand if I couldn't go on. I'll be totally honest, I should've kept in better sync with him and I felt terrible that my 2nd project fell behind schedule, but I really found myself totally engulfed in putting out fires in my personal business. Nothing went according to plan. I didn't abandon his project though, I finished it and got it to him a little late. I was just looking at it again today and I saw some problems I hadn't noticed before, so I sent him a patch.
It's really only now that I'm starting to get back a bit of time where I can do things like write this. I sent him an email telling him about this thread, but I'd bet he's asleep now.
