What makes Sienna Miller totally 'anxious'?

For every Miley Cyrus and Kim Kardashian who use social media to share (or
over-share, as the case may be), there's a Sienna Miller.

The Brit actress, who's in two films this awards season, tells Paste BN she will never
be on Instagram, Facebook or Twitter:
I have no desire to be in contact with that many people. Life is hard enough
as it is. Being a good friend to the people I genuinely know and love takes
up enough time when you’re a mother. To have a dialogue on that level would
make me anxious. I have no desire to share my life in that way with anyone.
I’m happy about it.
