"Gayle, look at you! You're... you're so... tall!" said Sally. Gayle continues to look at Sally from her hunched position.
"What do you mean, Sal? I've always been this tall!" she says, with a wink. Sally isn't buying the joke.
"Come on Gayle, this is serious! What happened to you?"
Gayle began to explain everything, from running into you during her jog, being unexpectedly assaulted with a water gun, which she later found out was actually some sort of magical size changing device. She even left in the bit about outgrowing her clothes while you watched, which made you blush and look away, catching a glimpse of your mother looking disapprovingly at you. By now, Gayle was kneeling in front of Sally, and still the same height as her. Your mother turns to you.
"So... you found a gun... which can change peoples size... and you decided to shoot Gayle?!" she said.
"I... I didn't realise that it was... you know, a size changing gun!" you retort. Your mum merely points at her giant friend, who is now rolling her eyes in innocence. Pretty cute for someone so enormous.
"So, what now, Dan?" your mother continues."Can you shrink Gayle back down, or is she stuck like this?"
You point to the dial on the side of the gun which currently points to 'Grow', allowing Sally to see that there is a 'Shrink' option as well. Sally paces around for a moment, seemingly weighing up the situation, or at least trying to make sense of it before looking back up at Gayle.
"It's pretty cool being this big Sal, especially since people used to call me short all the time." the tall woman says. "Why don't you try it?" she continues with a wink. Sally looks unconvinced, but before she can make her mind up, Gayle does it for her. In an instant, Gayle uses her increased strength to quickly whip the gun from your hand.
"Hey!" you say, but Gayle isn't listening. She inspects the settings before handing the remote straight to Sally.
"I'll even let you choose what to do first." says Gayle. Sally's eyes widen, knowing what power she holds in her hands. She saw how much fun her friend was having, and didn't have the heart to shrink her down, but if she got much bigger, then she might cause some serious damage to the house. She was nervous to try it on herself as well, so the only real option... was her son.
