I really really want a pony more than anything in the world, id give up everything i have for one, but my parents just wont buy me one :( they think its more exspensive than it actually is and they dont know anything!! I know my mum wants one too but my dad just wont listen! We go on holiday a lot because my dad is turkish and it would be hard i know, but i know all the comitments i would have to make and i know what i have to do every week/day/month, so please anybody share with me how they got a horse or how i could make my parents get me one? thankyou xxxxxxxxxxxxxx
