How would I express my ability not to do something?
"I cannot dig" means that I definitely cannot dig. But how do I express my ability not to dig? The first thing that comes to my mind is "I am able not to dig", but I was wondering if there was a better way to express that.
In essence I want to say something like "I can (not dig)"; parentheses are just for clarification.
Ok, so in order to clear things up, I tried to think of a better example. Lets imagine that I am walking in the park and see some big guy bullying a nerd. In this case I would like to say "I am able not to interfere, but I will!" (or in our case what I would like to say is "I can (not interfere), but I will!").
And someone working in the circus might want to say "I can (not fall) while walking on a narrow plank".
And the main question is - is it possible to express those examples using "can"?
