Yeah, I am bad about that one. I understand why I am wrong, but 55 years of habit is hard to break.
I had a blind programmer working on my team 10 years or so ago. I used to walk him down to coffee machine and buy him a bad cup of coffee every day. One day he says, MSF, could you please stop taking the Lord's name in vain. I said "Jesus Christ Mike, that is going to be a tough habit to break."
He is lucky I did not say Jesus F------ Christ.
