Talking to myself

The other day I was walking along the road talking to myself.
Suddenly, I realised the presence of a man walking beside me, on the right.
I looked at him.
He too was talking to himself.
Relief.
I actually ventured to say Hello to him.
He didn't respond, but noticed that I had said something to him.
I saw him remove his earphone from his right ear.
Sorry, I was talking on the phone, he said.
Caught on the wrong foot, for a moment I didn't know what to say.
I said, Hello.
He had a broad smile on his face.
And replied, Hello.
We moved on.
