Bumping around the downstairs of someone's house usually means that they are up to no good and so hearing it made the person delighted is not justified.
Context: "I heard someone bumping around the downstairs of my house last night after I had gone to bed and it scared me half to death."
Hypothesis: I was so delighted when I heard someone bumping around the downstairs of my house last night after I had gone to bed.
Based on the context, is the hypothesis true, false, or unknown?
