Seeing stars

This was some time ago. We were doing our work in school, when -- as it too often happens -- we stopped working and started talking.

I don't know what led to what, but an ex-classmate (he has since embarked on a different course) began talking about his romantic escapades.

"You know, when I was in JC," he reminisced. "I blindfolded my girlfriend and took her to the rooftop to see stars."

I realise that it was supposed to be something exotic or exciting, but at that point in time, it sounded anything but.

Barely able to keep a straight face, I turned to Z (whose attempt to do the same was betrayed by the hint of a smile) and couldn't help but inquire: "Blindfolded -- how to see stars?"

With that, we dissolved into uncontrollable laughter. When we finally looked up, he was still staring at us in bewilderment, before the realisation of what he had implied registered on his face.

"Crazy girls," he huffed, and stormed off, sending us into new fits of giggles.

(This is not why he decided to change course, right?)
