Happy Birthday!
A personal special day announcement. Most likely the school have a ready supply of these to give to the children on their birthdays. I wonder if they go so far as supplying a birthday treat at some point during the day such as a little cup cake adorned with a little lit candle for them to blow out. Further still such as some fee paying establishment a party would be laid on but at this state run school like these along this road it’s going a bit far unless you have a generous parent and teacher association that puts money aside for such occasions.
