Most writers use subject and object pronouns correctly in simple sentences:

I report for work three evenings a week.

The members of Vogon Soup invited me to lunch a few weeks ago.

But when a name or second pronoun is added, some writers can get thrown off and use the wrong pronoun:

Me and Sally often work the evening shift.

The members of Vogon Soup invited her and I to lunch a few weeks ago.

When you’re using a pronoun paired with a name or another pronoun, mentally omit it so that you can figure out the correct pronoun to use:

Me often work the evening shift.

I often work the evening shift.

Sally and I often work the evening shift.

She and I often work the evening shift.

The members of Vogon Soup invited I to lunch a few weeks ago.

The members of Vogon Soup invited me to lunch a few weeks ago.

The members of Vogon Soup invited her and me to lunch a few weeks ago.

If any of the correct examples above startled you, practice making the mental omissions whenever you find paired pronouns in your writing. Soon you’ll be choosing the correct pronouns without even having to think about it.
