Usage notes

 * When "I" or "me" is used with a conjunction, it is often advised that it is better (more polite) to refer to oneself last. Thus it is more common to say my husband and I than I and my husband. In such cases, the prescriptive rule is to use the same case form one would use if there were only one pronoun, thus my husband and I for a subject of the verb rather than the more colloquial me and my husband. I's is a result of making I possessive by adding rather than, as would traditionally be done, using.
