Given the task definition, example input & output, solve the new input case.
Given a sentence in English, provide the sentiment based on its empathetic direction. There are two possible classifications: positive (happy) or negative (offmychest).
Example: was down for a long time , wanted to show off what changed all that , my mermaid hair .
Output: positive
This is considered positive sentiment since the speaker disjuncts "was down for a long time" with their new changed hair insinuating a positive sentiment; therefore, it is correctly classified.

New input case for you: if it was n't for seinfeld ....
Output:
negative
