Hello, this message is for Mr. Tanaka. This is Sarah from Dr. Miller's dental clinic. I'm calling to remind you of your appointment for a routine cleaning tomorrow, Wednesday, at 2 p.m. However, I also need to inform you that our building's parking garage is currently under maintenance. We suggest you park in the public lot across the street. We will validate your parking ticket so you won't have to pay. Please call us back if you need to reschedule. Thank you.

您好，這則留言是給田中先生的。我是米勒牙科診所的莎拉。我打電話是為了提醒您明天（週三）下午 2 點的例行清潔預約。另外，我還要通知您，我們大樓的停車場目前正在維修。我們建議您將車停在街對面的公共停車場。我們會幫您驗證停車票，您無需支付停車費。如果您需要重新安排預約，請稍後再致電我們。謝謝。
