I got my neighbor a 510. He has terminal cancer, it makes me sad. It all came out of left field when he found out. It has spread from his lungs up his shoulder, and now only has use of one eye. His family is struggling financially. This too makes me sad. It was hard having to wait to be able to afford to get him one. He uses it all the time now. I'm having a hard time with all of this. I've dealt with enough death in my life. I hope I helped at least with slowing the process. He smokes a lot. I hope he really always uses it.
