It's been a long vacation. Last month, my aunt and uncle returned work, so they needed someone to look after their child. I offered to give them the hand. I had thought I was able to do that but things turned out so differently.
First, they fought from time to time but I couldn't stop from it. Then, the mess they made really annoys me. At lunchtime, I was busy preparing food while screaming to stop them beating each other. I wished I have not made that crazy offer. To her great relief, my grandma came that afternoon, which meant that finally I was able to go home—after cleaning up the garbage everywhere and collected the toys on the floor. How a busy day!
