I personaly don't see why you what to spend money on this game so badly.
I've been playing this game for a little over 3 months and haven't spent a penny.
I really enjoy this game but to me, I can spend an our or so on my mist energy
and then I can spend the rest of my time playing football or soccer with my
friends.

You have to understand that your mom is only doing what's best for you. I am sure
she doesn't know how this game works. She probably doesn't know that if you don't
pay with real money then you'll be playing longer.

It is ultimately her decision. Try and show a little respect to her and before jumping
to any conclusions, try and consider why she does what she does.
