Hola, antes que nada... Que la frase "Tengo mucha tarea" no se te vuelva costumbre, es un consejo. En una universidad no te tendran compasion.

Ben’s day. 
When I woke up this morning, I found my dog, Fox, waiting for me. He wanted me to take him for a walk. I was too hungry, so first I had breakfast. I had a glass of milk and a piece of toast. Then I washed my teeth and put on a track-suit and a heavy coat, because it was really cold outside. Fox was already impatient. We both went out, and walked to the park near home. He ran and jumped, and pursued some passers-by. He also destroyed some pieces of furniture somebody left on the road. I sat on a bench all the time, wishing I could be inside my warm bed. When my hands were frozen, I decided it was time to go back home. Fox didn’t want to, but I pulled hard and I managed to take him back. When we arrived at the front door, I realized I didn’t have my keys with me, so we stayed out in the cold for more than an hour! Fox was happy, but I was late for work!

Ojala te ayude!
