Accusing someone for something when you are the one at fault is not a great feeling and makes a person feel bad about themselves.
Context: I blamed my oldest son for losing my headphones but I found out later I was the one that lost them.
Hypothesis: I felt just great about myself when I accused my oldest son for losing my headphones but later on I found out that I was the one who misplaced them

Is the hypothesis incorrect? (Yes, no, or unknown)?
