Why do people start going on about their issues when you are going through a hard time? Do they think that helps?

I just got laid off from my evening job. I’m okay for a month or two, but after that am really going to have problems paying my bills. I was talking to a family member about it. Instead of trying to be encouraging, they started going on about all their bills coming up. Also, this:. Well, you’re birthday is coming up. You’ll get $20.00 for that.
Really? Really? Guess my problems are solved now.
Why can’t people just listen and not try to make it all about themselves?
