Nope, they want you to do more than they ask, they just don't tell you. Took me a while but I finally figured that one out at the age of 18. That little extra can sometimes go a long way...
When I wanted to bring my Rosy home, I had asked my mom a few times and finally I just told her I'm bringing it home, it's going in MY room, I'm the one caring for it and that was that. Now she loves the snake but my other ones all have to go to the Pop's place. Then again, I'm now 20 and I don't think this method would work well for a 14 year old, since I got this particular snake from my work to which I drive myself
Patience is a virtue...
