John got up out of his bed and wrung his hair out, then got to his locker and got his pants on, his shirt and jumper, then got an air horn.
"What's that for?" Mel asked.
John just walked into the Bathroom, quietly and stuck the airhorn over the shower curtain and let 'er rip in every sense of th--
BLAAAAAAAAAAAAAAGGHHHHHH!!!!!!
...damn. That IS loud!
Luca was immediately taken by surprise and pretty much jumped out of his skin, fell down into the bathtub and took the shower curtain and the rod to hold it up with him.
John just walked out casually, straightening his sunglasses and savouring the victory.
"That's what it's for." He replied casually as he walked downstairs.
Luca, meanwhile was left to pack his senses together. He turned off the water, got out of the shower, got the curtain back up, dried up and got his clothes on. He already had a plan for revenge concocted. A fart-cushion full of jam to be applied to his chair on the shuttle.
He came downstairs and sat down for breakfast, and John was already there, eating a bowl of cornflakes.
"Mornin' sunshine." He said calmly as he took a sip of orange juice, "I trust you slept well."
"Yeah yeah, indeed." Luca said casually as he smelt the milk for impurities before pouring it. Long story about that.
"So - what are you gonna buy today..." A quick exchange of glances over the last bit of sugar to sprinkle over the cornflakes, "...at the weapon emporium?"
"Oh, I dunno. Maybe some more..." He eyed the sugarbowl, "Ammo."
They both leant over the table swiped for the bowl - and grabbed it at the same time.
"I see!" John said as he tried to get his teaspoon into the bowl, trying to fence off Luca's teaspoon, "I was planning to do the same!"
Dad just looked at the two in combat over a bit of sugar and shook his head at them while resuming reading the paper.
