I disagree. When I was seven, I used to get bullied a lot at school. I observed that all of the kids with big brothers did NOT get bullied so I wrote a single wish on my Christmas list that year - I wanted a big brother.

In the following spring, my brother was born. I was not impressed with the result at first, I was no longer an only child and THIS THING was not much use with my bullying issues. However, the boy grew and grew and, roughly around his sixteenth birthday, went past my own 5'10", finally ending up at 6'3".

Pedants would say that makes him my bigger brother but the terms of my order to Santa were completed - it's my own fault for not having specified a delivery date.
