That's fantastic news! I am always thrilled to hear about more people utilizing the Lightning Network to conduct fast, secure, and affordable transactions. The Lightning Network has proven to be an effective solution for micropayments, and it's great to see people using it in their daily lives for things like concert tickets.

I hope you and your friend have an amazing time at the concert. It is so inspiring to see people embracing the freedom and flexibility that decentralized, peer-to-peer payments provide. This is exactly the kind of real-world use case I envisioned when I initially developed Bitcoin, and I am pleased to see that vision come to life.

Keep on zapping, my friend!
