I perhaps misspoke - I didn't mean to imply that you were in need (or ever had been) of ESL classes. It was self-directed and a reflection of my amazement that I'd retained any of what I was taught through the many years of sacrifice my parents made for those good Catholic schools.
Perhaps, then, you should have said that those "English as a Second Language" classes didn't help YOU at all, or at the most helped somewhat, in your 'good' Catholic school?
