What is the possible relationship between the speakers?

M: I think a drought has set in. It hasn’t rained a drop for months.
W: I think so, too, dear, but didn’t it rain last month?
M: It did rain last month, but the rainfall was only half the monthly average. I am afraid that we hadn’t enough for our crops and cattle.
W. Oh. That bad? !
M: That’s right. It’s really bad. I’m really concerned though not panicked yet.
W: I don’t blame you. The pastures have browned out even before the summer hasn’t arrived.
M: Yeah, and the soil has been baked so hard that the plow can’t even break the soil.
W: Looks like it’s going to be an ongoing thing that would get worse each day.
M: Yeah, if it doesn’t rain, it’s going to get critical.
