Precision: my younger brother is 10 years younger than me, so in my case the "elder brother reference" is in its full potential. He looks up to me for some things, for other things he needs to look down on me. It's coooooool to be an elder brother like that hehehehehe. I do have an elder brother myself, but we're only a year apart. And he's the married with kids type, so I really am the one who's more in line with my younger brother's student life.
