He could have waited to finish the last bits of work.
He should have left an hour earlier.
He would have to leave now.
He could have called a taxi.
He should have driven to work.
He would have to walk the stretch to the station.
He could have taken the main road.
He should have avoided the tunnel.
He would not have missed the call.
He could have checked his phone.
He should have turned the silent mode off.
He would have woken up when they rang again.
He could have so easily missed the blinking phone as he stepped out of the shower.
He should have hurried for the meeting.
He would have missed checking the phone till he got to work.
He did not clearly see who was calling. He did not clearly hear the initial reprimands for not answering the calls.
All he did was feel grateful for having heard the words “you became a dad yesterday”
