Rob Kardashian was uncharacteristically active on Instagram on his sister Kylie Jenner's 18th birthday. But while the rest of his family filled their Instagram feeds with birthday messages for a now-adult Jenner, Rob had other things on his mind!

The now notoriously reclusive reality TV star was notably absent from Jenner's 18th birthday dinner on Sunday, August 9, at The Nice Guy in West Hollywood. And while his other siblings, Kim, Khloe and Kourtney, took to Instagram on Monday, Aug. 10, to wish their baby sister happy birthday and share photos of the fun event, brother Rob was evidently thinking about other (more random?) things.

Bringing his total Instagram photo count up to three, Rob shared two photos on the evening of his little sister's birthday. The first was a picture of what appears to be a bottle of Paul Newman salad dressing, which the Kardashian brother captioned with the simple words "RIP."

???????????????????? RIP

The second photo, which the KUWTK star captioned "MOOD!!" is a picture of Colin Farrell and costar Li Gong's epic speedboat scene from the movie Miami Vice.

Not that her brother’s lack of online attention appeared to bother Kylie at all. The birthday girl continued sharing party pictures from her high-profile party in the hours after her brother's random pictures were published — the most recent of which showed off her amazing lip birthday cake which she received at her afterparty on Sunday, held at Bootsy Bellows.
