I love this look! This girl that I worked with years ago...on her smoke break...would lean against the building wall, stare at car traffic rolling by, puffing on a cigarette, with a very relaxed look. At the time, I couldn't help but look at her, somehow her relaxed look made me relaxed.
Haha, I believe she's got something she was was up. Perhaps the puffing made her had peace of mind...but it is usually for a short time!
