Very interesting story! Now my question is why your mother did not get you both one. My mom was a pretty big on being fair, if one of us got something generally the other two either got one too or they would get something else that was the equivalent. This was usually a good thing, prevented us from fighting as much as we would have. Main uncool thing was when I reached a milestone and they got it too at the same time without having to "earn" it, like being able to go outside in the backyard without an adult... Only ones that I got to have and they had to wait for was ones that the partents had no control over, like starting school, not like they can enroll a 3 year old in kindergarten...
