Yep, I'm right there with you. I was replacing the brakes on my Civic this weekend and hit my finger with a rubber mallet and took skin off again. Sometimes I think wet paper is more durable than my skin lol. I can't even imagine hitting my finger with an actual hammer, yikes.

And a few weeks ago while taking off my rear bumper I scraped my pinky finger against some metal and ripped off all the skin on the outside of my finger. That took quite a while to heal.
