What don’t the speakers like?

Woman: Spring is my favorite season. I just love the cool rains. They’re so refreshing, and everything is so green and new. It always makes me feel so happy.
Man: I know. I love it, too. It’s really a beautiful time. I really dislike the summer months, though.
Woman: I know. I can’t stand the heat and humidity. I’m useless when the weather gets like that. But, you know, I think a sunny September day like today is nice, too. Very pleasant.
Man: Yes, this is also a great time of year. The temperatures are quite comfortable, and the colors are so bright.
