I am friendly to everyone is not horrible to me. And if you are at a group such as a parent and toddler group, of course you say hello to everyone and try and include them a bit.
But sometimes I just want to talk to actual friends, and that is fine too. So if I meet friends at the school gate, of course I will talk to them. Or if I invite people to my house for a coffee, I will invite friends. Sometimes I chat to someone I click with and will invite them to something too.
But chatting to friends is not a clique. And I do think it is misogyny. I have never heard a group of men talking in a pub, or at a school sports match, being described as a clique. They are a group of friends.
