Giving your jacket to your girl when she is really cold is what a real gentleman does. You won’t care about yourself even you are half-naked or you are cold too as long as you are sure that she is warmth. You will prefer her own health and condition rather than your own. I tell you, if you do this, she will always remember this in her lifetime. She will even treasure your jacket. She might hug it during her sleeps and still feel your warmth against her body. She might also smell it to know your scent because that reminds her of pure love and gentleness you give to her.
