Two moral lessons of the story:

.For Oscar: Never pretend to be something you're not and don't lie to make yourself look better because it's wrong and a lie is still a lie no matter what. Lies always have consequences and it could lead you to big trouble. Also, you should appreciate what you have before it comes what you had because you should listen to your heart instead of your head while following your dreams, and friendship and love is more important than money and fame.

.For Lenny: It is okay to be different and you are your own person. Always be yourself and you're perfect just the way you are. You can never change yourself and you can't let somebody change your personality because you are still your own person and it is best for others to accept you for who you are even if you are so different no matter what, and there will be someone who already loves you for who are you and expects the others to accept allow you to be yourself.
