Most people dont but I've had a couple of interactions like this. A guy from college just couldnt stop laughing for 2 minutes. He laughed so much that he was out of breath just coz i was making faces while being stuck on a word. ​ Other than that I've had ppl at markets or stores smirk but try to hide it. I can hear them laughing later. Kids are usually pretty cruel. All in all events like these shattered my confidence the most.
