Giggle loops

From "Coupling," a giggle loop is the reaction when it's a serious occasion and the worst thing you could do would be to laugh. So you supress it and think, "how bad would it have been had I laughed then?" so it gets worse, and worse and worse...

That's about all that's happened, except for going mountain biking in the Trossachs and walking in the hills behind T and C's place - both good fun but knackering.
