All asthma and allergy sufferers will know what I am talking about. It has been a tough old year. In addition, there have been several peaks in atmospheric pollution in Brussels during the hotter weather. When we have not wanted to scratch out our itchy eyes, or sneezed uncontrollably, our chests have wheezed heavily. But this night it rained, and it rained properly; not just a passing shower but a proper, long, downpour. I got a chair and sat out on the terrace and breathed in nice, cool and above all washed air. It was a simple pleasure and a delectable one.
