What Do You Mean, "Unfortunately?"

A few months ago, a boy at my school found one of the English teacher's Facebook page. His page was on public, so everyone could see his updates. He often posted about my school and how he should 'start bringing a metal bat into class' and 'he should join in with the fights'. Unfortunately, a lot of students saw these and decided to show the head teacher, resulting in him getting fired. #LFHisF
