Must I Return Someone Else's Lost Item If I Wouldn't Bother for My Own?

This source explores a limit within the mitzvah of returning lost property. If a person sees an item whose recovery would require effort they would not normally expend even for their own property, does the Torah still require the same effort for another person's item? The mapped unit connects this to dignity, proportional effort and the category traditionally described as 'an elder for whom it is beneath his dignity.' It is not a loophole for indifference. The source asks how objective duty and a person's normal standards interact. Practical application depends on the item, burden, circumstances and halakhic definitions and requires review.
