They sound ridiculous. I was invisible in my writing group - joined the committee for a while to try and make some connections. I've since left. It never really worked. I don't know whether they noticed I was there. I didn't feel like people cared, but I've never been miss popular. I accept it these days, but it took a long time. I wrote about it here. https://medium.com/fuck-niches/do-you-feel-undervalued-or-ignored-in-your-writing-group-3bf555af52a2
