This doesn&#x27;t happen when you&#x27;re throwing a get-together of 5-10 close friends.<p>It&#x27;s more frequent for me with parties of 100+ invites.<p>The way I accidentally don&#x27;t invite people is<p>1. I setup Facebook event.<p>2. I scroll through a list of my friends on Facebook.<p>3. As I scroll through I invite any friends I think would have a good time at the party and are in town.<p>4. Never realize I didn&#x27;t to invite Jake.<p>5. During or day after party I wonder why Jake didn&#x27;t come.  Then remember that he doesn&#x27;t have Facebook<p>I don&#x27;t think most people sit down and try to remember every person they know.  Then create a list of people to invite and then use Facebook to invite them.  I think they go through Facebook and invite the ones they recognize similar to the way I do it.  It&#x27;s also hard to keep track of who is, and isn&#x27;t using Facebook at any given time.
