Use of "I" and "me"

CBSE ADDA
"I" and "me" are both pronouns that we use to refer to ourselves. Use "I" when it is the subject of the verb, and use "me" when it is the object of the verb or follow a preposition (with me, after us, etc). Remember that"I" is always written as a capital letter.

People most often make mistakes using "I" and "me" when they are talking about more than one person. For example:
My husband and I are going on vacation to Hawaii. (correct)
My husband and me are going on vacation to Hawaii. (incorrect)
Linda, Janet and I are friends. (correct)
Linda, Janet and me are friends. (incorrect)
You and I are having a dinner tonight. (correct)
You and me are having a dinner tonight. (incorrect)

My parents took my brother, sister, and me to the zoo every year when we were growing up. (correct)
My parents took my brother, sister, and I to the zoo every year when we were growing up. (incorrect)

Note that we mention the other person(s) first. In the above sentences we can't say "I and my husband", "I, Linda and Janet", etc.

The easiest way to decide whether "I" or "me" is correct is to make the sentence using only "I" and see if it makes sense:

I am going on vacation to Hawaii. (correct)
Me am going on vacation to Hawaii. (incorrect)
