I would host a karaoke night with costumes for my friend who had a bad week. We would wear silly costumes (2 years ago for Halloween, I dressed up as a plug and my friend dressed up as a socket lol, another friend dressed up as an Enderman from Minecraft). We also had a karaoke party where we sang and danced clumsily 🤣. With my singing and dancing skills, I am sure it will cheer my friend up (costumes are definitely an awesome bonus for humor).
