He Ain’t Lying
This isn’t a bad story in the sense that it shines a negative light on rich kids. In fact, it almost does the complete opposite. The OP started by saying that his friend was part of the 1% of his country and was obviously exposed to various luxuries the rest of us can only dream of.
For instance, a home with a built-in wavemaker is much better than a regular old swimming pool. You could only know if you’ve tried them both, right? It turned out that the rich kid actually had such a pool in his home and let the OP try it out. 50-foot waves in an indoor pool? C’mon, even that sounds unreasonable, even for a mega-rich dude!
