Based on the idea of doing a selfless act for another, have you known yourself or anyone else to have done something self-sacrificing for someone they cared about? Would you, personally, ever do something like that for someone you loved? It doesn't have to be for someone romantic. Further than that, it's easy to say you will, have you ever actually done something like that, even when it wasn't easy, and may have even been a worse idea to do so compared to not doing so?
