A friend who slapped me in school contacted me asking to borrow 1 million won

This happened during a 6th-grade elementary school retreat.
I can still remember it vividly. I hadn't done anything wrong,
but I was slapped just because I was standing next to them while they were in a bad mood. It was in front of many friends.
Around 11 o'clock today, they contacted me for the first time in nearly 20 years, asking to borrow 1 million won.
I guess they don't remember the past. People never change. It's a hot day, and it's left me with an unpleasant feeling. lol
