So deactivating Facebook is good for you. I don't actually remember how long it's been since I deleted my Facebook account, but it's been a while. It's been long enough that I don't even remember if I missed it or not.
A side benefit long term is that the messaging system that PAC (Parent council at school) uses is Facebook. Evidently there has been much drama there and I've missed all of it. I'm happy to miss all of it and continue to just say no to any request that I join Facebook again to get in on the messages.
