A relative of mine is planning to file a case against his neighbor. His neighbor is aware of that. For the last several weeks, the relative is noticing that whenever he throws something like an ice cream cup or a chocolate bar wrapper (for instance, Dairy Milk wrapper), the neighbor picks that up and takes it home. The items obviously contain my relative's fingerprint. The neighbor is neither illiterate nor poor. In what ways can these be misused by the neighbor?
