First off, he's the only guy in the family. He was really close with Khloe Kardashian's husband, Lamar Odom, and they even had a little bromance going, but...given recent developments, it would be kind of awkward if he kept hanging out with Lamar.
We've also watched Rob struggle a lot with what direction he wants to take his life in. All of his siblings are basically brands in and of themselves and since Rob isn't a hot chick, he's had a little more trouble on the selling yourself front.
Speaking of being hot, Rob has struggled with his weight a lot in recent years. The guy loves to eat and he's been fighting the good fight on the battle of the bulge front, which makes him probably the most relatable family member as far as we're concerned. Still, that doesn't help him feel any better about his body...in fact, he skipped the family trip to Greece last year because it was going to be "flaunt your beach body" time and Rob wasn't feeling it.
Now, as the family is enjoying yet another scantily-clad vacay (this time in Thailand), Rob is hanging at home and tweeted yesterday that "no one will ever understand how much it hurts" and that made us feel super sad for him.
Sibling rivalry is alive and well whether any of us want to admit it or not...and to try to hold your own in that family, especially given that they're all freaking gorgeous and the world is obsessed with every move they make, we can totally see how selling socks wouldn't necessarily feel like you're winning at life.
We're totally rooting for ya, Rob and we're here if you need a hug...or a workout buddy.
