Yeah, yeah, what a nerd. He collects the periodic table. Well, I do. It's not the largest, but contains some of the more interesting and rare elements, and it sits in the display case in my room. So the fuckup begins when I order the element cobalt. It has to ship from Italy, where I get the elements, and jars, and it arrived broken, so I emailed them and they responded in a very wholesome and Google-translated email, saying they would replace the jar. So the jar arrives and I transfer the cobalt sample from some of the other storage containers into its designated jar. Everyone would be fine if it stays in the jar. My girlfriend is at my house at the time, and I hand it to her to put in my display case, which she spends a while at. I assume she's looking at some of the cooler samples like gold, platinum, or gallium. I think nothing of it. Later on, her hand gets really red and itchy, like really bad. It looks like she stuck her hand in some poison ivy or something. And she's in a lot of irritation and some pain, so I think she knows what the cause is. Did you take the cobalt out of its jar? Yeah, I held it and looked at it. I know she did more than that, probably shook it around in her hand or something. For those of you who don't know, cobalt has an effect called contact dermatitis, which basically means you touch it and it makes you really uncomfortable. Once you have one reaction, you'll most likely develop a lifelong allergy. Cobalt is also known to cause cancer, but only with frequent contact. So now her hand is feeling a bit better, but it looked terrible. There wasn't much anyone could do about it, so that sucks for her. I had to deal with the fact that I handed her a very toxic metal and didn't tell her. Yay for me. Made your fuck up and I'm an idiot.
