Health Check-up

Had my health check-up today. Good news: I grew taller. Bad news: I'm underweight. When they drew blood, it was fine at first, but then it got super itchy after a second, I really wanted to scratch it. Almost failed the color blindness test, even got the numbers wrong. One character in my name couldn't be typed, so they just put a '?' Someone next to me wrote it out and I asked, they said it was '커' (keo). ㄎㄠˋ
