People smoking and spouting their evil puffs on my face (won't you just quit? It is bad for everybody involved). Cyclists not stopping at traffic lights and/or pedestrian crossings (you are not the most at-risk on the road, you know, pedestrians are). Bad advertising at the cinema (massive screen: use it properly). Phone fiddling while walking/driving/peddling (give it five minutes, five). Casual walking up to someone's desk, farting, walking off (it happens, it happened, urgh). Photos of food on Facebook. Anything too personal shared on Facebook. Facebook.
Contradictions? Nono, I love those.
