In the sentence below, should the bolded word be prepare or prepares?
When my family eats at home, my mom or I prepares the meal.
Normally, I would side with the verb agreeing with its corresponding noun in the sentence. However, since this is an exclusive or, where it's either my mom or I doing the preparation, that means that it would be my mom prepares or I prepare.
I'd like to avoid writing it like the sentence below, as it just sounds a bit awkward.
When my family eats at home, one of either my mom or me prepares the meal.
I was unable to find any existing questions that covered my scenario exactly. Most deal with (person) and I or the order of the two verbs in the sentence.
How can I write this using the my mom or I syntax?
