After drinking in a bar

My teacher from Middle school picked me up at a bar in the early morning (Middle-aged woman, never smiled, kept warning me to finish my homework, be a lady, don’t play with boys, I was very afraid of her).

But this time was quite chill, we walked back home, and kept sticking colorful tapes on our hands, red/green/yellow, until there are full of them.

She asked me to show her where the classroom was, apparently she didn’t realize the school was torn down, I had to find the exact location out of the ruins for her.
