A Tribute For Tia

Alistair is a seventeen year old boy with hardly any friends -unless, of course, you count the one guy that's been following him around since they met. His parents are useless at being parents, always working late and never there for either Alistair nor his younger sister, Tia.
Even though his parents don't know the first thing about him, they decided that he was depressed. So, they sent him to a shrink.
He begins skipping school after he begins talking more and more to a young girl, Maya, whom he met while applying for a job at the local music store.
They're just friends, though. He swears.
His life was seemingly adequate until one day, when he and his sister are home -alone, as always- she doesn't reply when Alistair knocks on her bedroom door. He had no idea that she was actually the depressed one, but he realises his mistake when he finds her, dead, hanging in her closet.
He finds a diary entry of hers that tells him all of the things that Tia wanted to do in her life, but was never able to do.
Then, he decides to do them all. Starting with a kiss on top of the Eiffel Tower.
