Have you ever been told you made someone's life better?

If you’ve been stalking me you know that I’ve been all over the US and have met quite a few different people on the way.

I’ve had quite a few people that I’ve met that have literally told me that knowing me or having me in their life at that point had really helped them in their life.

Recently the shit has hit the fan on my side and it’s forcing me to move again and probably for the last time. While I was still able to make it to work my co-worker said to me, “How can you smile knowing the doom that’s coming?” He was referring to the recently trouble I’m having. I said, “Why not? It’s already in motion and I’m currently in a good mood, so why not?”

This is just an example. I’m not sure if this example gives form to the others that told me I helped their life, no the co-worker didn’t say so, but I’m having trouble understanding how I did help them.

Have you helped someone’s life to the point they tell you so? Have you inadvertently helped someone’s life and only them telling you informed you so? Have you gone out of your way to help someone’s life or change the quality of it?
