A comment from a colleague today, "Eh, Adele, you have really gained in the US." As in, gained weight. It's not considered rude in Africa to say something like that. It's more a compliment, as if to say, "It is clear that you didn't struggle for food..."
Fortunately I had decided prior to the comment already that I'll be watching what I eat. It's hard, though, when it's culturally offensive to decline food, even if it means you're having a second dinner.
