Stealing credit
When your boss suggests that she will "take it from here", politely resist and insist that you take responsibility for presenting your own work. Let her know that you are confident in your own abilities to take it further. Thank her for her support but continue to resist and insist that you be allowed to stand up by your own work. Just be assertive and polite. Ask her to explain what puts her in a better position than you to present this work. Since no one knows more about this project than you do, who is better equipped than you to take it to the next stage?
