Spoon in microwave

Let me just say I’ve been having pregnancy brain. Two days ago i went to a restaurant and brought back some leftovers. I forgot I left the spoon in the container, so I stuck the container in the microwave tonight and didn’t give it a second thought and walked away. Came back, retrieve my food, opened it and saw I really left this metal spoon in the container....anything could’ve happened....now I’m not hungry anymore. I feel silly for not checking😓.
