Sometimes on mumsnet or some other forum I will post a reply to a persons post, hopefully saying something supportive or comforting and sometimes it will be somewhat revelatory. Other times you just post your favourite washing powder or who your weird crush is and in some ways it feels like you are taking part in a conversation except it isn't.
You never know if anyone reads what you wrote, if it was any help. People rarely reply or even do the new thanks thing and its fine I probably don't either that much but I was just thinking that in many ways we are just all talking to ourselves more than to each other.
