Oh!
And I hate... hmmm....
Old folks who yell at me for biking on the sidewalk (I don't know if this stems from some local tradition of strict adherence to laws or what). Sometimes, I like to take it easy and not risk my life in the speedy, sometimes life-threatening lanes of Helsinki traffic... I, and hundreds like me, occasionally (and probably ilicitly) bike on the sidewalk. Not if it's crowded, mind you, only when there are little to no pedestrians around. Invariably there is always some grouch shaking his cane at me - scolding my insubordination.
Perhaps he would have had a happier life if he had not spent so much time waiting for the little red man to change to a little green man at the crosswalks? (another weird habit here -- jaywalking is somewhat of a new phenomenon here, even when the roads are empty).
They just like their laws, I guess.
