I carry around small knitting projects I never know when I get stuck in a waiting room for more than an hour and knit one, purl few,smiling and keep an eye on other patients and the doctor's cabinet door, not to miss the doctor's call.
The doctor's nurse stopped by, admiring my work,and start chatting about crochet and knitting. Take the knitting with you next time and you will not get bored waiting to see your doctor.
