Having spent an hour skipping through the adverts on a recorded program, I find myself trying to skip the ads on a live one too. (There's also a fault on my remote: it's got an OK button, but it hasn't got a No it f***ing well isn't OK button.)
I once poured the kettle into the coffee jar instead of the mug, but the occasion when I made myself look the biggest twit was when a woman with an A to Z stopped me in the street and asked directions. I showed her the way on the map: left here, right along there.... etc. etc. She looked puzzled, and then asked me to show her again: left here etc. etc. Then she asked again, and again. By the time I was beginning to think she was daft or something, I noticed that every time I showed her a right turn I was saying left, and left instead of right.
I felt a left idiot.
