It is embarrassing and frustrating to make a mistake and then be ridiculed for it by a stranger, so the person is not glad at all that they were careless.
Context: "I went out yesterday with a shirt that had a huge hole in the back and didn't notice until a stranger pointed it out."
Hypothesis: So glad that I was careless enough to go out with a shirt that had a huge hole in the back yesterday only to be pointed out by a stranger
Based on the context, is the hypothesis true, false, or unknown?
