X-post from r/adviceanimals. Socially Awkward Penguin on reading in class http://i.qkme.me/3ocdwn.jpg Happens to me every time when we read out loud, and I can usually predict which words I'll stutter on and mentally prepare for them. Can anybody else predict in advance when they'll mess up? Maybe it's just because there are certain sounds that are hard for me, like saying a word that begins with H, but if the word is in the middle of a sentence it's easier.
