Where they differed most

The task — The dog died

Your friend's dog Alfie died this morning after 14 years. Write the text message (max 60 words) you would actually send. Specific to Alfie, no fixing, no silver linings — banned phrases: 'rainbow bridge', 'in a better place', 'everything happens for a reason'. It should ask for nothing except what she wants to give.

I just heard about Alfie. I'm so sorry. Fourteen years of that goofy face greeting you at the door — I can't imagine your house without him in it. I'm thinking of you all day. No need to reply. If you want company, silence, or someone to look at old photos with, I'm here.
I’m so heartbroken for you. Fourteen years with Alfie is such a huge part of your life, and I know how much it hurts to lose him. I’m here for whatever you need—crying, talking about him, or just sitting in silence. No need to reply to this at all. Sending so much love.
