i'm the youngest of 3. my brother [he's the oldest] and i are extremely close; we can talk about anything with each other. my sister and i, on the other hand, aren't as close. we were inseparable when we were younger, though. but i think the difference in relationship is a matter of nurture rather than nature. my brother and i were both in marching band all 4 years of high school, both in the top 5% of our class, etc. my sister is the complete opposite in that regard. as the youngest i've always gotten the better end of the deal... pretty much in everything. i got a car before my brother did [relatively], my gas was paid for, i'm allowed to do pretty much anything i want [while my brother couldn't do as much at my age]. i was certainly given more opportunities, not because i was the favorite or anything but because my parents didn't know about these opportunities when my brother was my age.
