Law of Nature?

I'm still in Dublin and haven't had time for longer posts, nor for downloading and editing photos taken with my new (!) camera, so this will just be a quickie. My outbound flight made me wonder whether it was inevitable to share a plane with hordes of shrieking teenagers on their way to a "language holiday" whenever I fly to Ireland.

Aer Lingus = headache-inducing school-kids, it seems. At times like that I marvel at my many teacher-friends' patience! Last time I flew to Dublin, an Irish man remarked to one of the teachers when disembarking "I hope you've got enough Valium on you".
