["My neighbor passed away a few days ago. She was a nice older lady who'd always greet me when I saw her in the hall. Didn't know her that well, but she seemed lonely. I feel kind of bad for not getting to know her better when she was still alive"]
Thats really sad.  Im sorry to hear that.  Getting old stinks.  I feel bad when I see someone who seems really lonely
