of sentimental value.
You see a homeless guy and you don't give him anything and forget about him in 2 minutes tops. You don't really care. You have a plastic trinket. You value it because it has 'sentimental value'. You keep tons of trinkets all over your house. You never use them, but they have 'sentimental value'. You cry when one of those pieces of plastic gets lost. You care more about a piece of plastic than you care about that homeless guy.
