The more youth one has, the less likely it seems to parents that that child is the one who did it. Age decreases innocence, and parents tend to first turn to who makes the most logical sense as a culprit, often looking at concrete evidence later. Also, parents sometimes indirectly expect the older to be responsible for the younger sibling.
Either that, or the kid dabbled in the black magic of mind manipulation, found only in the forbidden tome of the secret library in Azeroth. If that’s the case… RUN!
So yeah, it could be either one of those, but I just can’t tell which is more likely.
If a person wants to be loved, and you give this person love, showing it with all your heart, but the person continues to like you less as a result, what do you think is really going on in this person’s mind?
