On Friday, the city of Lagos was on lockdown because of one wedding. The wedding of the daughter of the richest man in Africa, Aliko Dangote. I didn’t get the memo on time. Not until I visited social media and found that the first class wedding ceremony had not just been attended by the high and mighty of Nigeria’s corporate, social and political class, it also had in attendance one of the most famous people in the entire universe – Mr Bill Gates. And when the pictures taken at the event started to make the rounds on popular blogs and news sites, I fully understood why there was a huge buzz around the occasion.
