Dont forget to put yourself in their shoes also, if you open the door to a "respectful, we cant make it" call, they may be more likely to communicate to you, even if they decided to go somewhere else. If you think about it, say they found Day Care from a "family friend" instead. OF COURSE, you would understand them choosing someone they know over someone they don't, however....it still would be nice to hear that from them rather than wondering what happened? alot of times we think the worst. "they heard you were'nt a good provider" or "thought your rates were too high".....nip all your worry in the bud by having this convo when you plan the meeting. Before you get off the phone just let them know: "I understand you are in the process of "looking" right now, and may have other calls to make or appt to attend, and I completely agree with that choice, choosing a provider is VERY important and may take time and many interviews to find the right one. However, please keep in mind, my time is very important not to mention I would like to think I would concider letting another provider know, I may not be interested but thankful for their time. Please give me a call and let me know either way, if you will make it or not. I look forward to meeting you."
