The first paragraph describes a person who feels nervous about an event that is coming up. I'm nervous about my presentation on tomorrow. I have been working on this for weeks and keep thinking of all the possible ways that it could go wrong. I worry that I will forget what I am supposed to say or trip on my way to the stage. I know that I shouldn't be worrying so much but I just can't stop myself. I'm looking forward to my vacation next weekend! I am going to spend the week with my friends at the beach. I cannot wait to soak up the sun and to swim in the sea. I am also excited to try out new restaurants and explore the city. I'm excited to enjoy a break from my work.
