It's different
The exchange between Sky and Chris replayed several times in Chris's head as he returned to where he had initially planned on going. And it was only now that he began to wonder if he had just unconsciously chosen the brother over the sister. He had done that on impulse. But he knew that even if he went back in time, he would do the same thing again.
He broke out of his reverie when he saw Rachel outside the door with her phone in hand and a little transparent nylon bag with two bottles of Sprite inside it. It looked like she was about to call him when she looked in his direction and cancelled the call when she saw him.
"Why are you coming from that direction? Did you miss your way?"
She put her phone inside her backpack and took out one Sprite and a straw, which she handed to him.
"I went to the gym." He answered casually and received the drink from her.
