"Were" is used for:
* Plural Subjects: When the subject of the sentence is plural (more than one person or thing).
* "You" as the subject: Even though "you" is singular, it takes the plural form of the verb "were."
* Past Tense of "to be" with "I" and "you": While these pronouns are singular, they take the plural verb form "were" in the past tense.

* The cats were playing in the yard. (Cats is plural)
* You were at the party last night. (You takes the plural form)
* I was tired, but you were full of energy. ("I" and "you" take "were" in the past tense)
