Politely ask to breed her.

"Hi," you say to the couple, giving them both a friendly wave.

"Hi there," the woman replies, her voice soft and melodious. "Can we help you?"

"Well," you explain, turning to address the woman in particular, "I was just wondering if you'd mind if I bred you real quick."

Immediately, her small, polite smile blossoms into a look of real happiness. "Actually, I'd love that!" she says, sounding genuinely enthusiastic. "I've been thinking about having another baby." She turns her head to catch her husband's eye. "You don't mind, do you honey?"

You glance back to the husband to see him crack a smile of his own. "Not at all. I think that's a great idea. Especially with a friendly young man like this as the father."

"Perfect," says the woman. "I guess I'll be a few minutes, then."

"No problem," he assures her, turning back to their cart. "I'll work on the shopping while you're at it. Take your time!"

As he wheels off, the woman turns her face back to you. She's still leaning over the cantaloupes. "So, how do you want me?"
