Trick or Treat? [Harry Potter Oneshot]

"Come on kids, it's time to go, or there'll be nothing left!" Ginny hollered up the stairs. As if by magic, James was at the bottom, opaque in cloud, as he was going as a ghost - Nearly Headless Nick to be precise, but the muggles wouldn't know that.
"Yeah guys! Hurry up!" He echoed.
"One minute!" Albus called down.
"But-"
"James, stop whining." His mother scolded him.
"Yes mum." He replied glumly, slouching down. But his posture was regained slightly when a mass of messy jet-black hair came thumping down; Albus had arrived, dressed as giant pumpkin.
"Wow Al, you look great! My little boy's grown up!" Ginny cooed at him.
"Yeah, yeah, whatever. We just need dad to hurry up - finally!" James exclaimed.
Harry came down the stairs, clad in midnight-blue robes, with a large, silver beaded. In his arms was Lily, who was being a vampire.
Ginny ushered them all out of the house, and into the muggle streets.
The Potter's were going trick-or-treating.

This is a oneshot for Wattpad's contest.
