aw happy ending! *smiles* great job

Capitalize your title properly.

For the love of god don't write stuff like "flashback" and "flashback end". It's just ridiculous.

Dialogue is written as "Hello," he said or "Hello!" he said, never "Hello." He said or "Hello." he said or "Hello," He said or "Hello" he said or Hello he said. The only exception to this is if the next sentence doesn't contain a speech verb, in which case it's written as "Hello." He grinned, never "Hello," he grinned or "Hello," He grinned. Note that something isn't a speech verb just because it's a sound you make with your mouth, so generally stuff like laughed or giggled is in the second category.

Furthermore, if you're breaking up two complete sentences it's "Hi," he said. "This is it." not "Hi," he said, "this is it." or "Hi," he said "this is it." And if you're breaking up a sentence in the middle, it's "Hi. This," he said, "is it."
