too much information

I'm in the breakroom having a three way convo with co-workers. The subject of piercings and tattoos came up. And then the subject of how fast the skin heals came up. And then my co-worker brought up how her skin has problems healing. It would take her a month just to get rid of the redness left by a pimple. She kept on going,telling us about her new belly button ring and how the skin around the ring probably isn't healing properly. Of course, the graphic description isn't enough. Before we know it, she stood up, pulled her shirt off her pants and showed us the belly button with the said ring with the said redness.

" It isn't infected, is it? "

It took me about five seconds to come up with a response which consists of one word.

"Um...."

Ten seconds of silence. She was saying something but I couldn't help but stare at her belly button that's right in my face. Mean, the guy who was with us was silent the whole time. I couldn't risk looking at him in fear that I might give him an icky look. It seemed an eternity before I came up with a reason.

" You're probably allergic to the jewelry. But it doesn't look alleric. It's just red. "

I hope I kept a straight face.
