Whose fault is it?

I woke up around 5am, checked email, worked out for 40 minutes, and fed family. Once everyone was out of house, I cooked today's dinner, coconut-lemongrass pork, washed dishes and checked time. It was still 9 am. I thought today was pretty productive. So, I decided to ramp it up more. I had lots of ricotta cheese in the refrigerator and need to use it up. I picked ricotta pudding cake recipe. Actually I hesitated for a second to use the bundt pan since washing was not as easy as rectangular pan. Anyway, I buttered and coated flour well. It seemed ok to me. After baking and cooling down, I flipped the pan. Cake didn't come out. I gently push the butter knife at the edge. And, ta-da!
The pan ruined my ricotta pudding cake!
Bummer. As long as I remember, it was third time to ruin my cake. That must have been why I hesitated to use the pan.
I gave three opportunities and the pan failed.
