Let's take them one at a time. The first,


  She might be only 28


is an example of great understatement, similar to when we say, 


  You know you might have helped us. 


The person is actually making a dig at the person by using might to imply "it's the least you could have done." 

I think that this is another example of understatement. The person is saying something like "yeah, she's only 28 but wow... " 



In one possible scenario, I can see that there could be some doubt but in the other I envision I don't see any doubt. In the first scenario, a child, maybe an orphan who found out who their parents were, makes a judgement that the parents, who, having lived close to the Barrow [a river?] must have walked along that __.

The second, it's a child who grew up with his parents and is describing a routine that the parents were seen to have engaged in. This is the would of reminiscing. 

Examples: 


  I remember when I was sick, my mother would stroke my head and sing softly to me.
  
  When I was a young lad, my father would take me fishing every Saturday morning after chores. 


Usage of "might" and "would" to indicate doubt
I have some income from Amazon Associates that is paid to me automatically every few months. I don't raise an invoice and Amazon doesn't create one for me. Amazon does specify a date when the payment amount is calculated and then a week or so later, the payment arrives in my current account.

It looks like Gnucash expects me to raise an invoice and assign it to a customer before it can be entered in to Accounts Receivable. The Gnucash documentation says that users should never create entries directly in to Accounts Receivable. Even if I try this, there's no option to select a customer (eg, from a drop-down list), but only to type a customer name, which makes me wonder if the transaction actually gets tied to a customer in the Gnucash system.

So how can I debit non-invoiceable amounts due to Accounts Receivable? Is this possible, or should I be handling this transaction another way?
