>"Hey. Hey Twilight."
>Just ignore her. She'll get bored and stop.
>"Twilight. Hey, Twilight."
>You hear the sounds of wings re-adjusting as Rainbow's smug voice gets closer.
>Just focus on your book, Twilight. noosphere theory is a good enough blocker for voices.
>"Twiiiiiiiilight."
>You can feel the grin on Rainbow's face and hear the cooing of a foal as she invades your space and presses her cheek to yours.
>"Psssst. Twi."
>You growl and finally turn to the irritating pegasus.
"What? What is it?"
>Grin never fading, Rainbow backs up and turns to her side.
>On her back nestled between her hunched wings is her month old son, who seems content to doze on his mother's back and soak up her heat.
>The tiny colt yawns adorably, showing off tiny nubs of very distinct canine teeth.
>"Hey, Twi. See this?"
>The pegasus ruffles her wings, pulling your attention to the foal again.
>"See this? I made this."
>Rainbow puffs her chest out proudly, tuft on full display.
>The smug that Rainbow is radiating is almost too much.
>She cranes her neck around to nuzzle the little colt, who giggles.
>"Hey, Twilight. You should make one." 
>If there wasn't a foal on her back, you'd throttle your friend.
