ASL anyone???

No I am not talking about age/sex/location crap. I am referring to American Sign Language (ASL).

On my way to work, I saw a young lady who looks a little lost at the Metro station. Being friendly, I asked her if she was lost. She immediately started signing as fast as she could. I haven't used sign language in years (background: I have cousins that are deaf, and I am hearing impaired), and I had to tell her to slow down. She finally asked where is the Hoffman Building in proximity to the train station. I pointed her in the right direction. She appeared really grateful and relieved. She thanked me immensely and went on about her way.

I walked the opposite direction feeling really good about myself, but in the back of my mind I wondered how long she had been standing there looking or trying to ask for help, and no one answered.
