While cultural differences *do* count for a great deal, I can't help but focus on three details mentioned in the article:
1. The wedding is "the first of its kind, in more than a century" where these individuals live. Even if he is 112 (has anybody checked the Somalian Half-Rotted Goat-skin Birth Certificate Registry?) this sort of thing hasn't happened in his lifetime.
2. Local people----people who, presumably, share this gentleman's cultural inclinations----expressed doubts and concerns regarding the age difference. Not everybody did... but, then, I'm sure there'd be a few "love knows no bounds" whackjobs saying the same sort of thing if this wedding had taken place in the United States.
3. He "waited for her to grow up" whereupon he "used his experience to convince her of his love for her." I just, can't wrap my head around this. The second part doesn't sound bizarre at all; it sounds like what every "playah" I've ever heard says about every girl they've ever been with. The first part, now, that's downright... WTF is up with that?
