I ignite the string and watch fireworks fly into the darkness above. They divide into red rockets, blue Catherine wheels and green sparklers. Puffs of colour dazzle the night.
‘What can you see?’ my sister asks.
At first all I can see are fireworks, but as each one flashes in my eye I can also see mortarboards hovering in Cathedral light; walking sticks digging into mountain passes; skiing across Canadian ice; sailing across burnt horizons.
I see us.
Just like fireworks, we brighten the cloudiest of skies.
