I keep in touch with mine just fine without Facebook. I use my phone every now and then for actual phone calls and sometimes even meet them. In short, I do what people have been doing years before Facebook and I don't feel like I'm missing out on anything. But then again, what works for me doesn't have to work for everyone.

Neither snow nor rain nor heat nor gloom of night stays these couriers from the swift completion of their appointed rounds.

You can't, Facebook is the only way.

You don’t have to use Facebook like a daily newspaper. There’s nothing wrong with just using Facebook like the Yellow Pages. It’s there when you need it — if you need it.
