It is fun being a vet (兽医). I like it because although it is hard work, every day is different! It all depends on what is wrong with the animals that come in.
At my clinic(诊所), I work long days on Mondays, Wednesdays and Fridays, and short days on Tuesdays, Thursdays and Saturdays. Sunday is my day off so I can spend some time with my family.
My day at my clinic begins at 7 am. My clerk opens the door, turns on some music, and makes everyone a cup of tea or coffee. My assistant (助手) cleans and feeds the animals. The phones start to ring and people make appointments. This is a very busy time of day!
At 9 am, pet owners start to arrive with their sick pets. Appointments take up the whole morning. At midday, I stop for two hours. I don't examine（检查）any new sick animals. I use these two hours to have lunch and do all my paperwork.
At 2 pm. I start to see sick animals again. At 5 pm, three students from a local school who love animals arrive to help out. They are very kind and warm-hearted. I am always happy to see their smiling faces!
From 5 pm to 7pm, I continue to see sick animals. Then, at 7 pm, we close our doors and the clean-up begins! We tidy the clinic, and feed and clean the animals. Of course, we also stroke (轻抚) them and give them hugs! Then, we turn off the lights and go home. This is the type of day I want to have.
I'm very happy being a vet, though unexpected things sometimes happen!
