I used to believe that Down Syndrome was an extremely mean name for the condition. I thought that down part somehow referred to people that have it being "below normal people."
It wasn't till I took biology that I learned it was named after a doctor.

Interestingly enough, my captcha includes the word "phenotype"

When I was a child, I thought that there was this woman who was stalking me, going to all the places I went to. I recognized her face at malls, convenience stores, movie theaters, and even on vacation on the other side of the continent. I was bewildered.

"Why," I asked myself, "do these slanted, vacant eyes, jowly cheeks, and slobbery lips haunt me so?" I could not figure out why I was seeing that same woman everywhere.

Well.

Turns out I was just seeing various women with Down's Syndrome.
