Yes Sir!

Lately when we ask Andrew to do something, like “Andrew come here, please”, quite often he responds in a very teenage tone, “I am coming.”  

To which we respond, “You don’t say, ‘I am’, you say, ‘Yes, sir (or ma’am)’”.  

So twice today, in regular everyday conversation the words “I am” came out of my mouth.  Once when Andrew asked me if I was holding onto my bag, which I answered, “Yes, I am.”  Both times Andrew promptly told me that “we don’t say ‘I am’, we say ‘Yes, sir!’”.
