I've had this idea for a meme/comic for a while now but I just can't seem to get it right when I draw it :/

Short Girl: *climbs out of car*
Short Girl: *gasp* My legs hurt!!! It must be growing pains!!!
Her Tall Brother: But we were just hiking for three hours-
Short Girl: *shushes him* No need to be jealous, bro. Soon, I'll be taller
than you.
Her Tall Brother: *facepalms*
