By Mistake

 A long-term associat calls
inquires about my welfare.
talks generally, concludes
he dialed me by mistake

Another one messages,
before I could begin reading
deletes them,  I heard 

his answer ” I did it by mistake.”

My gate creaks, a burly man
wishes me, before I could reciprocate
 He cries ” Oh”,is that you?
 I came by mistake.”

Finally, the postman drops a letter
in the box, returns a little later,
pulls it out in a hurry, remarks
* I slipped the envelope by mistake”
