Awkward Introduction

Do you ever meet someone for the first time and then walk away feeling like you were completly awkward? The answer is most likely yes. Because we have all, at times, felt like we gave the worst first impression. I have a habbit of smiling really big and not being able to stop smiling. Afterwards all I can think about is how creepy I probably looked. We all have our own awkward introductions. It might be an over sized smile, a too quite or too loud "hello," a really bad hair day, a lazy day outfit to the extreme, etc. Share your awkward introduction story.
