Where am I

Today, I was coming back from work, and I was going to get a ride from my brother to get home.

Well...this has been routine from some days. As usual , I got onto train and my cell phone rang and here goes the conversation.

Bro: "Where are you"

Me : "I am in the train"

Bro : "Where are you?"

Me: Thought in a split second :oh couldn't hear me..."I am in the train"

Bro: WHERE are you ?? (slight irritation in the voice)

Me: Thought...Come on...I told you I am in train..and then realize the emphasis on where..."Oh!! Just crossed blah blah station "

As I was thinking that he should have asked me where the train was ... I remembered this joke and smiled for a minute.
