Happy when no response for courtesy call back

Found a missed call in my phone. But I was too hesitated to call back. Or something else prevented me to give the courtesy call back

(Definitely the caller was not at all my enemy)..

But somehow I forced myself to call back.

And you know, there was no response from the other side.

And I felt so relieved…I was so happy that I did not have to talk anymore and I haven’t broken any courtesy rules.

Why did I think in this way?

Am I so rude…;)

Is this just a play of my mind..?

(Definitely, this play happens very occasionally only and not at all often. )
