Hi mom. I'm David. I made a reservation for dad's birthday last weekend. However, the restuarant is not open this weekend. It's terrible. I didn't check my reservation in advance. I am so sorry. I think we'd better find another restaurant for our family party earlier. Pops up in my brain. I know a really good Vietnam restaurant near my place. Right now, I am calling there. I will check if I can make a reservation for our family party this weekend. Also there are so many people in our family, around 20 people. We need 5 tables and a private room. Mom don't worry about it. I will solve this problem. After I make a new reservation, I will call you again. Bye mom.
