Best friends are the ones with who you can have a transparent discussion. Including a reality check, which can be harsh. If they don't do it, who will ?
That's not the tone I got from the post to which I replied. As they put it, 'Strange advice' - as in, 'Why would I treat myself as poorly as I treat my best friend?' I took it for a joke post (hence ":^p").
I'm going to assume you read the read the article and know the answer to your question.
To me, your comment reads as a cheeky way of saying that not all people are fluent in overt compassion and that this is fine.
I would agree, as long as there is an underlying implied compassion in these relationships, and that both parties have understanding of this. We are all human at the end of the day, and the need for social support is universal.
So swearing at myself, basically? Strange advice.
