Undervalued Employee

"I was the ONLY one who knew how to unjam the printer at my old job. And it was a lemon - it jammed at least once a day. I quit the job because I was overworked and unappreciated. My replacement left in less than a year. I hope they're suffering without their little resident unjammer. Thanks for letting me vent."

The Family's An Open Book

"Didn't need to know the reason I'm mums least favourite child and I certainly didn't need her to tell me what colour my step dad's pubes are. Didn't need my Grandparents to tell me that they had sex the night before on the couch I was sitting on or my grans favourite position."

I wish I didn't know about as Demodex or eyelash mites.

Oh, you didn't about them?

Prepare to have your mind blown.

There is a community of mites living in the pores of our faces.

Ever wondered why your face randomly itches when there's nothing visibly making contact with your face? That's because these little stubby boring worms–that are a distant relative of ticks and spiders–are having a party inside your fleshy dwelling, and they are grateful for its host to extend the welcome mat.

You're welcome.
