People need to seriously stop being so judgmental here. I have seen this same situation more times than I care to recall. It's normal. It's what happens when people die. So stop acting like this is weird, because someday you'll do it too. And also stop it with the materialism judgement. We all know this isn't about a bag. It's about relationships and emotions and expectations... To respond to the OP, I would wait until the dust settles in your friend's family and then encourage your friend to talk to her sister about it. These things set cracks in relationships that are truly unnecessary. If they can talk about it without being bitter or angry, they might be able to work it out. Otherwise the last memories your friend has with her mom could be tainted, meaning your friend's relationship with her sister could be tainted as well. And we all know that would be awful.
