Pablo López
On August 21st my sister was 11 years old, and my perent and I went to celebrate her birthday at the shopping center.
Then when we returned home, we went to my grandpartents' home because they had a present for her.
when we came into the yard, we saw all her friends, and behind them our favourite singer: Pablo López sang for my sister, because it was her 11th birthday.
We danced and sang all the time because we enjoyed the party a lot and we couldn't imagine how my  gradpartents' could have contacted him and made him come to their yard.
My sister and I enjoyed the concert a lot and we will never forget it.
