My Part-Time Job

Today, I would like to talk a bit about my work. 
Having just graduated this year, I got a job immediately after the last exam in order to earn and save up money for further education. At the moment I’m working as a cleaner in a school for disabled children. 
It’s quite a challenge! Mainly because I’m not used to, nor like, cleaning “professionally” like this, but also because the children are present while I’m there. I’m not really afraid of them, just very aware of where they are. 

The school is divided in three groups or areas;
Red is for the children who are most disabled and sit in wheelchairs most of the time, and they are also the ones you can interact the least with. This is the group I’m assigned to, but I help out in the other groups too. 
Children of Green are at a medium level. They also use wheelchairs; however, they are much more active, especially this one girl, C, who likes to “help” me. She’s a real tease, and she knows it! (She likes to make trouble?)
As for Blue, here are the children who can walk. And run, which I learnt the hard way when one of the girls tried to escape when I was about to clean her room. Her and boy L are the ones I’m most cautious about, since I’m never sure how they are going to react. I like boy SK, though, he’s such a sweetheart!

I have never worked like this before - yes, I’m one of those teens whose parents are willing   to pay - so working 3-6 hours a day, 4 times a week, is quite suitable for me. For now, I’ll be there for about 2 months, which means no vacation for me this summer. But hopefully, I’ll be able to stay there longer, or find another job, because I won’t continue my education until  after New Years, and I really need money since I’ll also be moving out and living by myself around that time.

I've probably told you this before, but your English is awesome. I can tell you've been learning it for about a decade.
