To knit or not to knit...

Here are the lovely places/times it is appropriate to knit:
1. Waiting for class to start.
2. Lunch...well any meal break really.
3. At home on the couch
4. In bed before going to sleep.

Here are the places I have found not to be or have predicted not to be good knitting places/times:
1. While driving in the car.
2. While showering or bathing.
3. In bed while asleep.
