When was the most stressful time of your life? Did you learn anything from that experience?

i am remembering one of the stress full time. when i worked in guesthouse in Busan, The guesthouse belongs to my friend\'s parents. my friend recommended me to his parents and then i could work there. one day my friend visited guest house while i worked in and he want me to improve my English skill. suddenly he did role playing. i actually didn\'t have confidence and didn\'t ready about that. he keep asking question like customer again and again. it felt really pressure, not kidding he forward to my face and shout out asking asking asking... he didn\'t give time. i was embarrassed first time and then really pressure, felt bothering. it was really stressful and terrible. i want to punch his face to be honest. i did stand for it because he is my owner\'s son haha. Then suddenly, tears came down. i was really sad, depressed, just all kinds of negative thins came to me. few minutes later, my friend apologized to me and the i decided i will master english one day, i will keep studying english
