When someone says “you’re supposed to be on my side“, they mean that they expect support, agreement, or loyalty from the person they are speaking to. It’s like being in a team game where each member is expected to support their teammates.
Here are two examples in sentences:
Example 1:
When her brother agreed with their parents about her curfew, she shouted, “You’re supposed to be on my side!”
Example 2:
When his best friend criticized his decision in front of others, Jack said, “You’re supposed to be on my side, not making me look bad.”
Now, let’s see two examples in a conversation:
Example 3:
Sally: Hi, Lisa! I can’t believe you told mom about the party.
Lisa: I’m sorry, Sally. I thought she should know.
Sally: But you’re supposed to be on my side!
Example 4:
Sam: Hey, Robert! Why did you vote against my proposal at the meeting?
Robert: I just thought there were better options, Sam.
Sam: But Robert, you’re supposed to be on my side!
So, when someone says “you’re supposed to be on my side“, they’re expressing their expectation for support or loyalty from the person they’re speaking to. It’s a way of saying, “I thought I could count on you to back me up.”
