We Are NOT Invincible

So yesterday I found out something crazy about someone I'm close to. It makes me think so much. We really have to be careful in life because we never know what could happen to us when we don't think. Thats why I try to be so careful. The sayin that you only live once. I never really agreed with that. Because to me when people say that it's gives them an excuse to get reckless. We are not invincible.
The person that I'm close to just found out they have HIV.
I was speechless when I heard. When they came home I knew something was wrong because the person didn't say hi when they walked in. Come to find out later that they are in they're room crying.
When I find out, I can't help but think of the stereotypes about people with HIV. I don't want to run away everytime I see this person. But it's hard because I've never dealt with someone like this before and I'm wonderin if I can still treat this person the same.
I suppose nows the time read and educate myself on the subject. Thank goodness that medicine has advanced the way it has. And that people are living better lives. It's still so crazy to me. I'm waiting for someone to say it was all a joke.
I know thats not going to happen.....
