It is a sunny and windy day today, the sky is clear and crystal blue. It is spring now, the temperature is the most comfortable in a year, which is between 10 degrees to 20 degrees, so even if sometimes the wind gets strong, it is still cosy to go out. But there is one thing annoys me a lot under this weather, my skin gets sensitive in spring, and I am allergic to the dust and pollen picked up by the wind...
