I say get one, I used to have a Hamster. They're fun to play with, if you do get one, get him a little rolly ball that he can go into.
Hmm... I don't know how well outsider help will do on this. The best I can say is just to ask her and take her thoughts into consideration. Also, clear out the haze and get to what's really behind this. When you can truly see from both sides of the fence, then decide if you want to buy the hamster or not.
