One could begin with the prickly heat caused by our ridiculously hot weather, the congested roads along the market caused by roadside traders putting their tables and sampling goods on the walkway meant for pedestrians. One might even begin with the bad roads poorly constructed by some greedy contractors. Or the constant regression of our economy that has caused the inflation of goods and made cost of living astronomically high, and standard of living unbearable for most citizens.
Say you just put on your dress and decide you want to get something from the market place, even from the keke or motorcycle you take to the bus stop, you start experiencing the anger of fellow citizens, with the keke driver shouting and uttering words like ''madam do fast enter, if you no wan enter, you commot make anoda pesin enter" even if you just hesitated for a second before climbing on. Then when you finally make it to the bus stop, you still have to put up with rude conductors and the ill-mannered drivers piloting the buses taking you to your destination.
Sometimes, it happens when you exit the bus, you'd have to shout before the conductor gives your complete change, and as the bus zooms off, the conductor angrily mutters curses and insults at you. Now, you're down from the bus, on the market horizon moving about to find what's scribbled on your list, you have to walk gingerly to avoid people stepping on you and then raining insults on you instead of an apology. Even when someone bumps into you, instead of a sorry, what you'll hear is "you no dey watch where you dey go?!
Going further into the nooks and crannies of the market place that are clamped and very tight with little room to pass, you probably start to sweat. Even when you ask for the prices of items you'd like to buy and try to haggle as usual, some of them still respond rudely to you as if you are the cause of their current hardship. You know, I vividly remember few years back when I was unaware of where I was going, I politely stopped a passer by to ask for directions, instead of him to help, he looked at me angrily, hissed and walked away. That was when I remembered what my teacher in secondary school told me is true, that the average Nigerian man is angry. Nowadays, everybody is just angry, people are frustrated. Nigerians barely get enough sleep and still wake up everyday thinking of how to feed and get even the most essential of things. For example, someone will toil, go through a day's stress, hustle to see if he/she can make ends meet, then the nigerian police or even sars will come from nowhere with their own wahala. Not to even talk of going home to face NEPA wahala and having to sleep through a hot night frustrated and uncomfortable.
In conclusion, our leaders are to blame for our situation and our predicament. Because a poorly run system leads to hiccups, and hiccups lead to frustration, and frustration then leads to anger.
OP, more than half of Nigerian population is angry for different reason or the other, that shouldn't be a surprise to anybody, this is expected, why won't one be angry, when governance has turn to persecution, there is unforeseen turbulence in this country, is just that Nigerians are very peaceful despite that the government has pushed us to the wall we keep adapting to every situation we found ourself, it is very shameful to be called a Nigerian because of the rulers of the day, how will citizen who are ready to give their best to the society continue to wallow in hardship when the government have all it takes to create enabling environment for foreign and domestic investors for the people to be accommodate in the said space, the sadness in Nigerians heart is becoming unbearable and swift action should be taken to avert the looming danger ahead.
