I was passing a mother pushing a buggy on the way in on a bike track that is always used by walkers too.....and she was kind to completely move out of the way, but just as I was about to nod a "thank you", I got a big fly or wasp go right down my throat and I had to hock it up immediately....the kid in the buggy kinda jumped....I got the insect up and out but by then I was passed the lady.....all quite confusing I'd say !!
