Every morning on the way to taking DS to nursery I have to go over a very steep bridge, it's also on a bend and on a rural, one car wide road.
After almost running into a car on this bridge a few times I have started to sound my horn as I go over it, to warn anyone who may be approaching from the other side. But every time I do that I think 'but what about the trolls that could be living under there?' and it always makes me think of you guys 
Shall I carry on pipping my horn, even though I may be potentially upsetting or disturbing any trolls that live under there?
