Yeah. I went with the mantlepiece thing because there seemed to be an unspoken "My relatives all expect me to keep this urn somewhere nice, since it's been in nice places since she died" thing going on.

If there weren't the peer pressure going on, I'd just scatter it somewhere meaningful to me, but not the person themselves, since you obviously don't know who the person was, nor what their traditions were. Though now the forensic pathologist thing sounds attractive.

(If I got someone random's ashes, but knew who the person was, I'd definitely pay for an appropriate burial in their tradition.)
