It also indicates that people face a number of constraints or difficulties that have to be managed in order to secure a certain standard of living and well-being. But are they really managing? Is it not just a matter of politeness to say that you are fine: that your situation is manageable? If politeness indeed blinds the true picture, then further inquiry into people’s livelihood should reveal who is managing and who is not. Philibert Maniaasie and Francisca Mweyang are both in their late fifties. They live a stone’s throw away from each other. Philibert has lived and worked in southern Ghana for more than twenty years.
