What I really hate-smokers. Smokers contribute to global warming and they get hooked on it. I mean, I don't understand how people can get hooked on smoking! It's disgusting! Everytime I pass by a smoker, I purposely make a very obvious face to show like I'm sufferring... Sometimes I even cough extremely loudly, so just that they will feel very guilty and stop smoking.

Pollution

Pollution, another cause by HUMANS. I really don't know what's becoming of this world. Why would humans, especially Singaporeans, want to litter? And the most common areas where they litter-canals. Canals are the main source where our drinking water comes from. So why do people still litter in it even when they know that's what they're drinking? I know that the government put garbage bins everywhere intentionally so that we can throw our rubbish in it. But apparently, there's no difference.

Rude

Humans...are plain RUDE. They throw tantrums, fight with people, swear bad words at other people, and many other things I don't want to mention. It's just in their hormones that they have all those things, but people can't always have what they want! They should learn to at least keep SOME feelings to themselves. Because they won't know, anything they say might hurt others, and especially emotionally sensitive people.
