'Flabbergasted' Hi everyone, my English teacher always gives me and my classmates something to read and some clips  to increase our skills during the free time. The last day of school he gave us a paper with some advices for the summer holidays. In the text there was the verb 'to flabbergast'. Personally I have never heard it and I'm wondering if you guys use it in your everyday life. Do you use it or do you just use the expression 'I'm flabbergasted' (the one I found on google while I was searching its meaning)'
