I think we should have a thread on daft triggers. The little things that have us cough, sneeze or yawn. Not the ones that send us into proper attack or anything.
Just the wee ones like someone rummaging in their make up bag at the next table at Starbucks this morning- cue cough, sneeze. Two minutes and it was all over as they'd left the shop.
Or coming down a twisty highland road with many altitude changes - makes me yawn and hiccup.
