Could have done it is not the same as would have done it.

I paid $40 for a slightly larger hole in my wall, a 3″ pipe and some goop….oh yeah and the knowledge on what to do with it all. Watching over his shoulder he didn’t do anything I couldn’t have done.

But just because I could have done it, I know I wouldn’t have done it. But now I do have the knowledge and confidence to execute the task if needed again.
