@Georg-Prime While I agree the mom primarily wants to ask Toono for advice about his experience, being a role model is not only for the son but also as an example for the people around him. When people see other's role models be/do good, people also become more accepting. Seeing female role models or leaders inspire people to be more confident, astronauts and the space missions inspired people to be scientists and engineers and be explorers.
I also agree the mom is making the right choice to let it be for now and not ask directly. But I think it also gives her hope that her son can be fine in their society because others seem to be doing okay.
