He finally showed up and I don't think she is happy

A female mallard duck swooped down into the pool with a splash yesterday. She probably thought it was a duck pond maybe because it looked that way. Due to the late start of spring, the pool is still covered and there is some water and leaves on the cover so I can understand this duck's confusion. She had a swim, perched at the top, groomed herself for about a good thirty minutes then she waited, and waited as if she was waiting for her partner. We kept our distance while doing our yard work and she seemed fine with us in the background. After sunbathing, swimming, waiting and just hanging out for half the day, she decided to take off. This morning she was back but she was not alone this time. Her partner finally arrived but they seem like an old married couple hanging out at the edge of the pool, not talking to each other. Could she be upset with him for his late arrival? Have you ever been kept waiting and how would you react?
