Gaslighting rarely has immediate results. Its effects are typically gradual, slow, and extremely subtle, which makes it difficult for the victim to spot the manipulation, which precisely is the entire point of gaslighting. The victim would be likely to dismiss this isolated example of manipulation as a random occurrence if it happened over a long period of time, if they noticed it in the first place, whereas they would be more likely to spot the gaslighting if it was done in a shorter time frame.
