I tend to get a blockage in my right ear twice a year (very narrow ear canals, apparently) - once in winter, which isn’t a problem, then again in summer, annoyingly usually in the days leading up to going to Green Man. Last two years have seen me enjoying the Friday line-up in glorious mono (a blessing in disguise, considering some of the bands).
Total relief when the levee finally breaks after a few days of olive oil, though. Gave my ear a wee scratch on the Friday night after getting back to the campsite last year and masses of black wax lodged itself on to my fingertip, completely cleared it in two attempts - could have heard a pin sneeze from 10 miles away after that.
Enjoy your lunch, everyone.
