Allen spotted an error

Allen viewed my new post after he came back from the night tuition class. Sharp as he was, he spotted a typing error in memories. "Dad, can you still rectify it?", he asked with apparent concern. I told him it is not retrievable-I have to live with the mistake now.

Allen made me feel uneasy at the fault. There is strong urge in me to make a rectification through another post. Here it is.

Sometimes Allen is more meticulous than me. Maybe I need to be sharper next time.
