Working at my primary school and capitalism

So this is like my 7th time volunteering at my old primary school. Its because my mum works there so I'm just helping out doing all the things she doesn't wanna do. But I'm not getting paid. And at first I was fine with that because its not like I work there. I didn't apply to volounteer. My mum just brought me in one day. But then my dad asked if I was getting pocket money... NO. It hadn't occurred to me because I've never got pocket money but its a fair point. Like im doing everything a teaching assistant would do but for free. I get you know volunteering. It is free. But I'm helping my mum out. Some pocket money please! I mean we are poor :p so I dont care too much but its still annoying that I'm doing things for free which anybody who earned just a bit more than us would be getting paid for. Capitalism is wack 

Also I'm not being spoiled bc like £2 is fine for me
