I never was very fun of my sister, she's a bit of a snob and we never got along. But a few months ago her attitude towards me changed completely and this made me be suspicious. I found the reason for her change. We both have the same father and my grand-mother from my mother's side died recently and left half of her money to me and half to my mother. My sister found out and decided to see if I would buy her something. I've decided to play along but not for free...
