The girl nodded agreement with the mans first statement. She was much warmer and the material of the coat felt great against her skin. For a moment she felt guilty for having dirtied this kind mans coat and then she decided she simply didn't care. Being warm was well worth inconveniencing a stranger and, considering what she had seen that day, things happened that rendered such a small problem obsolete. Having thought that through she began to feel silly for having felt guilt at all. 

A glimmer of light and the question "May I?" Bought the girl to attention and she realised she had let her mind wonder. The tiredness was beginning to get to her head. She would need to sleep soon. The girl watched the man make a gesture suggesting he wanted to treat her feet. Almost uncaringly, and yawning as she did so, she nodded. She would permit him to tend her injuries.
