Summer Learning Journey- End a Sentence

For this activity I had to choose a sentence out of three and end it. For full points I had to post 8 - 10 sentences.

I looked around and no one was there. It was my birthday and nothing seemed unusual. I thought my my friends were surprising me.  I heard foot steps down stairs, I went and saw a shadow.  I was freaking out. I went closer to the living room. Opened the door. " SURPRISE!! " It was my friends and family. I was so surprised and happy.
