All the time! My son says that I will talk to anybody and it's true!
I always think back to a time when , during my lunch hour, I was in a queue at the till in Woolies and there was an elderly lady in front of me. Because the person being served was proving to be a problem for the retail staff, the lady and I got chatting about how things had changed in shops etc.
At last they opened another till and the lady I had been chatting to walked forward to be served but before she got to the desk, she turned and thanked me for the chat , saying that I had been the first person she had spoken to since she had last come into town at the weekend - it was Wednesday!
So those of you that stand there, refusing any social action with anyone standing within cooee of you, just remember that there are thousands, if not millions of people that live on there own with no one to talk to. Two minutes of your time cost you nothing but just that smile, hello, or a comment about the weather can make someone else feel a whole lot better about their day !
