I don't get a wedding or funeral vibe. I see it as an elderly man being visited in a nursing home (or similar) by his grown child. The child brought flowers and now the father wants to talk about the grandkids and missing his wife, the child's mother. He has nothing else happening in his life, so he watches the dog down the street and empathizes, because he too is just waiting around for the people he cares about to come visit.
