I liked frozen_alaska's thread, so copying it! Though this is a bit less empowering... Mine: Typing in alternating caps. j/k I failed my first driving test in less than 1 minute. I ordered cake batter ice cream with "strawberries and spongebob" mixed in. I left my cell phone in a taxi in Japan. Lost that thing. I missed a final last quarter because I was too lazy to check the syllabus. Just a small sampling. Thankfully, no life mistakes yet.
