What are you doing here?

I am in Spain. I arrived on Sunday at Barajas airport in Madrid and then I went to my hometown. It was a big surprise to all my family because only my parents knew about it. So, I arrived at my house, I opened the door and my uncle was there sitting on a chair, he moved his face and asked: "What are you doing here?". I continued giving surprises. I went to the kitchen and my grandmother was there, when she realized that someone was waiting at the door, she turned her face and looked at my, "What are you doing here?." And finally, my grandfather. He was sleeping, so I decided to wait until he woke up. I was talking with my family and then he went to the kitchen where we were talking. He looked at all of us and then he realized that I was there, "You are here! What are you doing here?."
Sunday dinner was great. My other grandparents and my uncles came to my home and we have a big dinner together.
I happy end after three days traveling to arrive.
