summary: 

 This 6 minute English was about punctuation. Without a punctuation, the sentence can be understood in a different meaning. I think it is very amazing that 'Let's eat, grandma.' can turn into 'Let's eat grandma'.

 I think using commas and periods at text is very important. It will be easier to read and understand the meaning.
