Final answer:
An 'I statement' in the given scenario could express the woman's feelings of being upset and disrespected because her favorite coat was not treated with care by her sister.
Step-by-step explanation:
An example of an I statement in the scenario where a woman becomes angry when her sister borrows her favorite coat and returns it with stains and a tear could be: "I feel upset and disrespected when you returned my coat with stains and a tear because that coat is special to me and it feels like my belongings are not being treated with care." This I statement expresses the woman's feelings and provides a reason for why the situation is upsetting to her, without placing direct blame, which can be more conducive to resolving conflict.
