Does it ever matter if you're not in your friend's other fb account?
Both my accounts are as real as each other. But as always, I hardly ever post about anything personal in any of them.
I never quite believe it telling the whole world, via a public post what's going on.
For me, the way to engage someone is still, spending time together in activities, conversations, having a time of good laughter together.
I love being with people, but tweeting stuff, or posting about my thoughts, engagements on fb is simply a scary thought for me. Nah, just text me. At least I know conversations is contained between us.
