Please tell me if I did something wrong

After having drinks and fighting with my girlfriend,
I arrived home in a designated driver's car.
Since the apartment parking lot was full,
I double-parked. My girlfriend got out immediately,
and the driver left. Then, my girlfriend suddenly came back
and said, "There's a spot here, park it here!" (with a serious, angry face).
I told her I didn't want to because double-parking can be considered a violation and someone might report it,
but she just looked at me with contempt, saying "Who would even see that?" and kept lecturing me.
Did I do something wrong?
