I think people assume that because you are natural, your hair should be long. They seem to automatically take how long you have been natural to equal how long you've "been growing" your hair. As though your hair had not been growing if/when you were relaxed and it began its growing once you went natural. And if you've been natural for a long time, the assumption is your hair should be long by now. The same assumption is not made for if you've been relaxed for a long time.
