It's wrong to try and dictate what your partner wears.
Anthony's girlfriend, Martha, gets a hat promoting a political campaign that grinds against his core values, as a human being.
Anthony doesn't want Martha to wear the hat when they're together.
Anthony buys Martha a new hat, that is more politically neutral, that he knows she will love because she considered buying it herself.
Anthony gives Martha an ultimatum, telling her that he will not be seen in public with here, while she wears that hat.
Martha finds the gift to be thoughtful and wears it all the time, and Anthony feels good that he gave her a gift, rather than complain about her political leanings.
Martha is offended and tells Anthony that she has every right to wear that hat, and Anthony regrets giving an ultimatum to someone he loves.
