Quick question: I have a child who has just started in reception and no older children, so I'm a bit new to school-related terminology. If there is a school sports day and a "reserve" sports day, what is the reserve sports day? I play a sport quite seriously and to be a reserve is to not quite make the team, so I at first assumed there was a second sports day for the less athletically gifted... then I thought nah, surely it's just a back up date in case of unforeseen circumstances... and now I'm really confused! Thank you.
