Tips for improving the intro of my story?

First off I'm impressed. You have a talent. It can only improve it you write something every single day, even a paragraph. Some writers aim for 5 pages a day - no more and no less. I love your first sentence. It sets the tone, and doesn't need changing. This is only my opinion, but it would be really neat if your parents were celebrating an anniversary of six years instead of four as the character is five. Two little others ones, could you find a better word than "gasped"? And, finally, I think I'd use the work "rink" instead of "lake". Other than that, you are off to a roaring start. Please keep it up.
