#3

Whenever I get on a bus or train, particularly a new one, I diligently research it beforehand—print out maps and timetables.  But no matter how prepared I am, I always have a sneaking suspicion that I am on the wrong bus/train, and it is going the wrong way/a new route even if I am staring directly at the map and it is following the path. 

This second guessing results in me hopping off madly, midroute, only to realize immediately this makes no sense and I was on the right bus and now have to wait 20 minutes somewhere random.
