As my sister came flying off her skateboard, I swear my first instinct wasn’t to laugh. First, I felt a pang of concern, worried that she’d hurt herself.

Followed very, very quickly by my instinct to laugh.

‘Oh shut up,’ Kira growled at me, wincing as she climbed back to her feet, hobbling to pick up her skateboard from where it had crashed into the gutter.

‘I’m sorry,’ I said between bursts of giggling, fanning myself with my hand. ‘You should have seen your face!’

‘Hilarious, I’m sure,’ Kira said dryly. ‘I could have been killed.’

‘Oh please,’ I rolled my eyes as she dusted the dirt off her new graze. ‘You would have been fine. Worst case, there’s plenty of great support coordination options for disabled people around Adelaide.’

‘You watch too much news,’ she said with a frown.

‘And you have two left feet,’ I stuck my tongue out at her.

‘Shut up!’ she kicked a pile of gravel at me and began to walk in the general direction of home. I jogged to catch up with her, feeling the infrared waves of mild-to-simmering anger rolling off her.

‘Is your knee okay?’ I leant down and said gently as we walked.

‘Like you care,’ she said gruffly.

‘I do actually care,’ I said, rolling my eyes. ‘Just a little bit. A tiny little bit.’

She ignored me, settling back into silence for half a block or so.

‘It stings a lot,’ she eventually relented with a sigh. ‘But I’ll be fine. No need to organise an NDIS provider for a disabled relative just yet.’

‘Good to know,’ I said, raising an eyebrow. ‘Now who watches too much of the news?’

‘It’s called a callback, idiot!’ she said, glaring back up at me again. I raised my hands in surrender and she trudged ahead of me.

‘I’m sorry I disrespected your burgeoning comedic talents!’ I called after her. She flipped me the bird without looking backwards, and I laughed out loud.

‘Okay, that was actually pretty funny. Wait up!’
