I think it's a bad idea. Yeah, it's only 3 and half years difference, but 3 and a half years is a lifetime when you're teenagers. Find someone closer to your own age. When she's nineteen and you're in your twenties, go for it.
Otherwise I hope her big brother whoops your ass.
God, so atrocious in the Old Testament, so attractive in the New--the Jekyl and Hyde of sacred romance.
-Mark Twain
If people are good only because they fear punishment and hope for reward, then we are a sorry lot indeed.
