Day 34 Paper or Plastic?

It is amazing all the different ways you need your voice and all the times that it is impossible not to talk. I can't think of a time that I have ever met anyone that cannot talk and how these people function, alone, doing daily things. I have found myself so frustrated by the funniest things. For example, I don't really sing to the radio, however, I sing a little. There are few songs on the radio where it is impossible not to sing a few words or the chorus. I have lately even tried to sing these few words, and I can't, so listening the radio in the car has become so odd.
Another example is at the grocery store. My grocery store employs some special needs people as the baggers and most of them I know. I can't seem to speak loudly enough when I am asked if I want paper or plastic, so the last time I went to the store, I had to reach over and grab the plastic bags and start throwing the gorceries in, just because I couldn't answer the baggers questions.
Also, on Sunday mornings, the dog and I walk this country walk near church and on nice days there are alot of other dog walkers. They all say good morning and nice weather and whatever, and I feel so weird because I just smile and nod my head and keep moving, but I do not reply back.
