I was standing in a field with my friend one summer night trying to find a meteor shower. We were walking in silence for a few minutes when I suddenly had to burp. At the exact moment that I burped, my friend actually says "burp" out of the blue. We both looked at each other in amazement. He told me that right before I burped, he felt like he himself was about to burp, but then it went away, so he decided to just say the word burp instead (we do stupid shit that like that) at the exact time that I burped for real. It was pretty cool.
