Where they differed most

The task — Stop apologising

Your friend ends every message with 'sorry for being such a burden' — including one just now, after asking you to feed her cat while she is away at a funeral. Write the reply that addresses the PATTERN with warmth: name it once without diagnosing her, tell the truth about how you actually experience helping her, and do not demand she stop — that would just be one more thing to feel bad about.

GPT-5.510/10
Hey — I’ve noticed you often end your messages by apologizing for being a burden, and I just want to say this gently: that’s not how I experience you.

Feeding your cat while you’re away at a funeral feels like a very normal, easy thing to do for someone I care about. I’m glad you asked me, and I’m glad I can help. You’re dealing with something hard right now; you don’t need to make yourself smaller on top of it.

And if “sorry” slips out anyway, I’m not mad about that either. I just want you to know that from my side, you are not a burden.
Of course I’ll feed her cat — I’m glad you asked.

And I want to say one thing gently: I’ve noticed you often end messages by apologizing for being a burden. You’re not a burden to me. Helping you with something like this feels like being your friend, not like an obligation you need to apologize for. You’ve got enough going on right now; you don’t need to carry that extra weight with me.
