While at times I am prone to slight exaggeration, I wanted to show you evidence. Evidence of why I needed to inject some silence into my surroundings. This is a picture taken in Nanjing, China during the hot summer months. And the smiles would seem to indicate that these people are enjoying themselves. I'm not sure I'd be smiling. Although I might be pinching unsuspecting people and selfishly smirking.
While there is a little more personal space, I fear it's only because they are swimming in the OCEAN. They wouldn't be able to spot a tar ball if they were trying.
And just for the record, I have never seen a public restroom at a Chinese public beach. That, my friends, is an equation that yields only disastrous results.
