How would you explain ‘heya’ in the context? But this afternoon, nothing yet to do in the empty barracks but take out every pair of pants from the foot locker and fold it up again. Or sit on the bed with The Odyssey. Until the head of Bull’s Eye appears around the door. All ears and smile, the half-bit haircut. “Heya bookworm. Too busy lollygagging, then?” “Too busy for what?” The book claps shut. “Noodle juice and cookies with Mrs. Hoover. Whatcha think, for what? An ankle excursion.” “K Street?” The smile disappears because the whole boy disappears. How would you explain ‘heya’ in the last sentence of the first passage? Thanks!
