<p>Well, I have friends in different circles, but I've never felt a problem with inviting them all to do something together. Like, I've got my best friend from home, and my best friends at school/friends from swing dancing, and friends from an organization I'm in... and at least a few people from each one is coming to my birthday party in a few weeks. I'm not worried... looking forward to it being really fun actually! </p>
<p>How do you know your friends won't get along? You never know!</p>
