There are a couple of old men sitting on a concrete bench outside.
A couple of older men are waiting for their wives to finish shopping.
Just because a couple of old men are sitting on a concrete bench outside does not mean they are waiting for their wives to finish shopping. There is no evidence these old men are even with their wives or that they are shopping.
