This whole thing has been blown up out of all proportion.
She seems a sweet girl and was full of contrition for the unwise use of Twitter. She is now being hounded by a cruel and merciless public and a militant group of cyclists for (in effect) confessing on the only medium on which she was comfortable to coming into contact with a cyclist.
As we are all aware, these racing cyclist hurtle at beakneck speeds (even the adjective causes me concern) through roads that are for the use of everyone, not just those with a passion for racing and taking risks.
There, on these roads, startled by racers whipping past her at absurd speeds, was our sweet, young and impressionable Tweeter. One of the cyclists clipped her mirror. Outrageous, but she appears (from her confessional Tweet) to have forgiven him.
For doing nothing more scandalous than Tweeting a confession, she now stands to lose he job, her career, her freedom and perhaps even her Starbucks loyalty card.
Give the girl (sweet girl) a break.
