tired of Facebook

Haven't logged in to my Facebook account in a while. I don't know, but it's like I've grown tired of it. Before, I can stay up the whole night just Facebook-ing. I'd play Farmville, Yoville, Buddypoke, and Restaurant City. I'd check out vids and links posted, and repost some that I find interesting in my profile. I'd comment on status updates and photos, and Like eveything, well, I like. But now, I can go on for a week without checking who added me as their friend, who replied to a thread, or who bought me in Friends for Sale. Ok. I'm officially weird.
