I drove myself to the ER with a broken right ankle. I pull up right at the front window to try and make it to the entrance....another patient and their son got me a wheelchair because i obviously couldnt walk and was struggling....I will say that again....another patient came with a wheelchair to help me. And...I walked out with a boot cast and struggled all the way....passing workers along the way.
Moral of the story....if you see someone struggling just help them even is its not in your "job description".
