In my college you have to give you roll call for every hour (for every class you attend) so yeah it was hell for me. In first year my roll number was 422 ,first few days I was able to say it easily but then I was struggling to continue after the number 4, i used to say it like 4-4-4 22! Every laughed at me so I just decided to say 22 instead of whole numbers This my roll number changed to E-16 , I was done for because I forgot my entire life struggle to say E or sixteen I missed almost a week of my college because everyone was laughing at me at every hour every day for a whole week Now it's third week since I got this new roll number and I have reduced my shuttering while saying my roll call, i guess after Experience the stress i experienced this last two weeks my body just kinda adapted but I know this adaptions will just vanish after a holiday or 3-4 day not giving my roll call
