"I love you too, Little Brother Thomas."
I'm so lucky to have such an amazing little brother. I take a second to make a promise to myself. I promise that I won't let him down.
A glance at the sky reminds me that I promised my mum that I'd tell him she loves him every single day.
I'm disappointed to realise that I've already broken my word.
"Mummy loves you too, Thomas."
"I know."
He grins happily at me.
"You do?" I can't help but return his smile.
"Tristan has been telling me every day."
His words surprise me.
Words abandon me though as I gape up at Tristan, catching sight of him in the light from one of the street lamps above our heads.
"You made a promise but I knew you couldn't keep it," he looks down at me with a shy smile, "so I kept it for you."
His words overwhelm me and I reach up to kiss him.
"Thank you," I whisper against his lips.
I snuggle into the warmth of his chest. He kisses me on the head before picking Thomas up, so he can join us in our embrace.
