Honestly, it just appeared in my way

Okay maybe not. But I'll blame it on being really tired.

Yesterday, I was in the tissue lab, and had to grab a bottle of media in the room next door. When I was walking back into the tissue room, I walked into a giant BL-2 hood. Most of my body was able to avoid the large metal item, but my shoulder took a big hit.

It was sore for a few hours afterwards, and then I forgot about it. Since it was my left shoulder, my backpack strap doesn't sit there, and I went on with my life.

This morning when I was using the soapy poofie thing, my left shoulder was sore when I was soaping the shoulder. I looked and saw the red, black, and blue colors there. I then remembered why it was there.
