Thaitralia: Night and Day
Kasem was busy making breakfast when Jett entered through the door, sweaty after his workout. Jett immediately went to get some water.
"Did you have a nice workout?" Kasem asked.
"Yeah," Jett said. "And now I feel ready for the day. Why don't you join me sometime?"
"Thanks, but it doesn't work for me. I'm too tired after a workout."

Jett was working on dinner when Kasem entered the kitchen, his head soaked after a workout. Kasem went to get some water.
"I'm going to take a nap," Kasem said. "Wake me when dinner's ready."
"I still don't get how you can sleep after exercise," Jett said. "Your heart should still be pumping. And all the endorphins and stuff…"
"And when they settle, I'm tired. See you later."
Some people feel energised and revitalised after doing exercise, while I don't. Regardless of the exercise, I normally feel very tired after a session. They normally say not to exercise too late in the afternoon or at night because it could interfere with your sleep, but I've literally used exercise as a sleep aid in the past. I actually googled if this is normal, and the result was that it's just how my body works.
