Have you?

Have you ever had a thing for somebody you knew you couldn't have? It's not a matter of you being too ugly to get them, but more like you too young. Or maybe they stuck on an ex. Or something else just gets in the way of making them yours.? And it's like one day that obstacle might be not so hard to get around but by the time that day has come they probably would have been happily in love with someone else. Urgh life's a BITCH.!
