Jobs

Most people would be happy with a job like me. I babysit for a couple down the road, have been for 2years now. I started when I was 13 which is good going. I've made over £1000 from them which I can't complain about. The job is good pay to say what I do. There's a few problems though... 1- they seem to take advantage of me on new years and christmas.
2- they never say when they will be back so I don't know how long to stay
3- the kid is a spoilt brat. :/ no other way to say it. She moans when I don't let her do what she wants. She's greedy and every time I come now, she thinks she can get her way and its really getting on my nerves now.
The thing is, a job is a job and its good. I can't complain about anything apart from the kid. It does involve spending my Saturday nights being bored shitless rather than being with my mates but I do it for the money. Now that I'm 15, I want a different job. One that makes me feel responsible and that my parents will be proud. Most people I know my age have part time jobs now. I wish I could be like them rather than having this job. :/ as I'm.writing this I'm working, just shows how much spare time I have haha... bye
