Part 3:
A few days ago my best friend was on vacations whit his family, and he told everybody something was going on, there were these beautiful flowers that he would like to give me, but the next day someone took them, these were not there anymore and we wonder who took them? so he looked for any other place but he found nothing similar, so he arrived kind of mad and told me that the flowers could not be my cause someone stole them, and I wasn't sad because I appreciate this cute action.
Explicación:
