This topic reminds me of the time I got a special / free birthday cake from a restaurant owner.
This topic reminds me of the time I had a perfect dining experience in a restaurant.
It was my last birthday, my friends threw me a birthday party in a restaurant. When we were cheering and laughing, one of the waiters walked up to us, and asked ‘who’s the birthday girl?’ My friends all pointed at me. And later, the owner came over with a huge cake in her hands, and she said, ‘Happy Birthday, dear.’ It’s on the house. I was so surprised, ‘cause you know, it’s common for restaurants to offer free noodles to a birthday girl, it’s kind of like a tradition, but I’ve never seen anyone who would send guests free birthday cakes. I was so overwhelmed that I didn’t know what to say.
And before I knew it, all the waiters and waitresses started to sing Happy Birthday. I have to say, it was such a pleasant surprise.
The cake is about this big (不要忘记body language). There are fragrant flowers on top of it. I’ve never seen that kind of cakes before. And the cream is so palatable. Normally I wouldn’t eat cream, ‘cause I find it greasy and too sweet, but that one’s different. The texture was really soft and smooth. The cake was fluffy and light, it could just melt in my mouth.
So, you see, this cake is really special. For one thing, it was just so delectable, and for another, it was the first birthday cake I got from a complete stranger.
So I have to say, that cake was really a pleasant surprise. It was my first birthday gift from a complete stranger.
So you can imagine, I really had a good time in that restaurant on my last birthday, and I’m really satisfied with their service.

Well, I’d like to talk about my 18th birthday, which is a special occasion for most people in China, ‘cause from that day on, we become an adult legally, and we start to have our own rights and obligations. So on that day, normally we would have a huge celebration, and I was no exception. My friends threw me a big birthday party in a coffee shop where the environment was awesome, you know, the music, the lighting and everything. All of my friends were there. We played board games, danced to the music played on the jukebox, sang along with the background music and took tons of selfies.
