The era of pinching cheeks is over. But that old and common gesture still flows in our blood: we have to look always that something or someone's glance makes us blushing.
I thinks it's because it's a sign of good health, good manners and good attitude, even if under that shadow that as a miracle appears on our cheeks, we all are much more similar to a witch than to a fairy.
But we are lucky, we live in the tera of perfect make up. So we don't have to cause ourselves some phisical pain, we just have to cause some pain to our credit card.
After all, aren't we living in the time where money can buy everything? Even a fake blushing.
