We know who you are now, so it is okay to come out of hiding. You should have known that keeping a secret like this were to eventually explode, but no one will be mad at you. You did give us one of the most iconic songs of all time ("Girlfriend") which taught girls that it is perfectly okay to be a home wrecker (Oh). Avril would have never been a home wrecker.
Many people would say that you look live Avril's "clone," but I would have to disagree. You have the face of an innocent newborn kitten and Avril has the face of a ferocious lion. She has the punk-rock look in her eyes and you honestly have more of a sweet, innocent look.
Avril doesn't dance. Your earlobes are different. She went from wearing mostly black to random colors and streaks in her hair. Her music used to be intense now she has cupcake socks? I bet the real Avril would rather eat nails for breakfast than cupcakes.
What we, as fans want, is to know what happened to Avril. As @givenchyass would say, "Like, I'm not saying Avril is dead, but Avril is dead." You were one of her best friends so you obvious know what happened, MELISSA.
Come clean and you won't have to be somebody else 'round everyone else, watchin' your back, like you can't relax. If you keep pretending, you'll look like a fool to me. Even though all this time you were pretendin', if you come clean now you can still have a happy ending.
The people who know Avril is dead.
