Not sure if I understand this correctly; avoiding such situations altogether seems virtually impossible. For instance, if people know you can help, you are in close enough relationships to have expectations of mutual help (e.g., friends or relatives), and you do not help, it is likely to be upsetting; while severing and avoiding all close relationships (particularly with less tech-savvy people, in this example) seems like an overkill. Or do you picture that non-positioning differently?
