TOD:
There was a time, not too long ago, when if you saw a person talking to himself you assumed that that person was crackers. Now, with cell phones, I see this all the time--and it still looks peculiar to me.
And I am amazed at how animated and sometimes how personal these conversations are. Alas, there is no phone booth to muffle the conversation and keep it private. People walk down the street, talking LOUDLY into their cell phones, for all to hear. Personally, I'd rather they keep it to themselves.
