i say get the snake! what is your mother going to do, really? that's what i did with the birds and the two kittens. sure, they were mad, but they got over it when they discovered how cute they were. and i'm responsible for them--i always take them to the vet and pay for their bills. i'm a grown woman! so are you--get the snakie!
(disclaimer: do not take any advice from me if you value living with your parents or having them finance your school--i think i just have 2 very special parents
