learn the rule: me or I?

• I and me are 1st person singular pronouns
• I is the nominative form and is used when the pronoun is the subject
• I need to buy some potatoes.
• I am not ugly.
• Me is the accusative form and is used when the pronoun is the object
• The potato hit me in the face.
• You are uglier than me.
• There are some exceptions:
• I can be used in more formal situations; me can be used in less formal situations, e.g.
  • Who was it?
  • It was me. (informal)
  • It was I. (formal)
• Me is used when following prepositions, e.g., "...behind John and me", not "...behind John and I"
• Things get more confusing when there are multiple subjects or objects in the expression
• The pronoun never appears first in an expression (as you always place yourself last)
1. Wrong: "[I/me] and my daughter went to the Zoo"
   Right: "My daughter and [I/me] went to the Zoo"
2. Wrong: "The bus hit [I/me], Bob, Jenny and Dave"
   Right: "The bus hit Bob, Jenny, Dave and [I/me]" *
• The same subject/object rules apply when determining whether to use I or me
1. Right: "My daughter and I went to the Zoo." since the pronoun is the subject.
2. Right: "The bus hit Bob, Jenny, Dave and me. " since the pronoun is the object.
• A simple way to check is by removing all the other subjects/objects and deciding if it still sounds correct:
• "I went to the Zoo" vs "Me went to the Zoo"
• "The bus hit me" vs "The bus hit I"
• Beware getting it wrong can change the meaning of the sentence
• "Jenny fancies Bob more than me" - Jenny is more attracted to Bob than she is attracted to you
• "Jenny fancies Bob more than I" - Jenny is more attracted to Bob than you are attracted to Bob
• Getting it wrong is pretty easy.
• It still makes you look stupid. And uglier than... me? Or I?

*Although this also depends on how you feel about Oxford commas.
