To Ken

 This is a note to a guy named Ken.  

 On my signboard in front of the building we hang a sign which says "One Point English Lesson". On the sign, we print a useful idiom or an interesting vocabulary word and their meanings in English and Japanese. This week we forgot. 
We were surprised to find a little note stuck to our sign which said: 
"Please change." It was signed 'Ken'.
  Ok Ken, we have changed
