As I have mentioned in other threads on this topic, one real problem is when people buy stars for dead loved ones, thinking they have gotten some permanent memorial.

Then they come to a star party or an observatory and demand to be shown the star.

If the astronomer plays along, then the astronomer is abetting a scam.

If the astronomer tells them the truth, then he is breaking their hearts.

I hate and despise the people who sell stars, because they force us to deal with this sad problem every year.
