It's fine to not understand things. Being condescending is a natural reaction to feeling challenged, I really do understand where you're coming from. It's not even your fault, really. Anyway, when you're ready, feel free to pick it up again, the material doesn't take things personally and neither do I.

Or I guess just not responding to any of the technical questions that have been brought to you. That's an option too.
