for all the kids starting school and have a "mean" teacher: the teacher probably had a rough day and snapped or something along those lines, my algebra teacher yelled at me at the beginning of the school year last year, but grew to love me and I loved her at the end of the school year. she even kept my end of year project bc she said I was an inspiring student !! just wanted to encourage some fellow students, don't judge a teacher by first impression !!! best of wishes to fellow students !!
