Oh boy....my story is also at your level of embarrassment. So I was at a Barnes and Noble browsing magazines about 3 years ago and I saw the cutest girl with awesome orange shoes on. I spent about 15 minutes deliberating on what I should say to her. So I decided to compliment her awesome orange shoes (like so awesome I would rock the pair and dance to Bruno Mars' Uptown Funk). I approached her and tried to say what I wanted to say....and the only thing that came out of my mouth was a weird sound between squeak and a grunt as my voice locked up. So here I am, with this cute girl giving me a strange look, and me trying to give her a genuine compliment, but nothing coming out my mouth. That was the longest awkward 5 seconds of my life (seemed like an eternity). I finally managed to say very quietly "you should know, those shoes are really cool....I thought you should know that" while her expression went from strange look to genuinely weirded and creeped out. To make it worse I repeated it again (but with fluency) and she responded with a quiet "ummm...ok?" Awkwardness intensified.... At this point my fight or flight gauge was on red alert pointing at "flight". So I hastily spun around and marched away, blushing really hard, feeling like a super creep, but sort of relieved the moment was over. It took me several hours to get over the embarrassment I felt after talking with a good friend of mine.
