A couple are under an umbrella with a child.
It is pouring rain outside.
People can use an umbrella to shield from sunlight or snow, so it cannot be assumed that an umbrella must only be used when it is pouring rain. An umbrella can be opened indoors, so it is not certain that the people are already outside.
