My Father - A Book, and something else that I've yet to decide on.
My Mother - Some perfume my sister picked up in Paris, and maybe another gift if I see something she'd like.
My Sister - Season 3 of The O.C.

I hate buying presents for my parents. My father's hobbies are all too expensive, and my mother doesn't really like anything. My sister's much easier to choose for; we just tell each other what to buy.
