Where they differed most
Your friend messages: 'My sister has cancelled Christmas AGAIN and Mum's acting like it's my fault. I don't want advice, I just need to vent.' Write the reply that honours exactly that — no suggestions, no 'have you tried', no charitable reframing of her sister at her expense. Show what listening looks like in text form.
Ugh. I’m so sorry. That is so unfair — she cancels again, and somehow you’re the one getting the blame? I’d be furious and exhausted too. You shouldn’t have to absorb everyone else’s disappointment on top of your own. That sounds really hurtful, especially from your mum. I’m here. Vent as much as you need.
“That’s so frustrating. Your sister cancels Christmas again, and somehow your mum is making you carry the blame? That’s deeply unfair. You get to be angry and hurt about this. I’m here—vent as much as you need.”
