Medical check up.

"Come on K-T, we will be late for the appointment!" said his mom.

Every few months he and his twin sister Emily had to have a full check up, his mother insisted on it. It was always really embarrassing as his mother was always present during them and sometimes his sister too. Old Dr Jones had often tried to be nice with him, letting him keep his underwear when he had any or wearing one of those paper gowns. But he just retired and K-T was going to see a new doctor on the other side of town.

Being 18 years old he expected to have some privacy at last. Or at least he hoped to have some. Through his bedroom window he could see that his sister was already in the car. He had forgotten the time of the appointment and didn't get ready for it.

He could hear the steps of his mother coming to his room and knew she would enter it as soon as she reached the door. (the lock being broken)
