Matching Tattoos and Death

I have a friend in New Zealand who had a friend in Ireland. I got a matching tattoo with my friend in New Zealand. She got the same matching tattoo with her friend in Ireland (and other people). Her Irish friend had a brain tumor and was dying. He's been dying for a long time, I think, but he's just now actually died and it made me really sad because even though I've never met or talked to him, I had the same tattoo as him and we were connected a bit. He must have been awesome to be friends with Jess, though. So I guess it's also sadness for a missed opportunity to be friends with him.
