one time I had a substitute for math and had a heavy accent. My name is Duncan so when he called my name he said "Dooncan" which is Ironic because my friends call me that just to mess around with me in PS4 parties.
I've actually had a pretty good track record with sub teachers. My name is Owain, and it's pronounced like Owen, so you'd think everyone would say 'Ow - Wayne', but no.
