We had one very honest and interesting comment from Rio at St. Helen's School. This is what was sent in:

It was hard when I was trying to get the same number as someone else. In the end I gave the number up. Sometimes I was given a card I didn't need so I gave it away to someone who needed it more. It was hard being silent as I knew which card people needed to give away to others and I couldn't say anything.

Thank you so much for those very thoughtful comments.  It can be frustrating when you think someone should give a particular card to someone else and you can't say anything!
