sadegh1979: What would you do suppose you go to a travel, but the flight is canceled, you return home and you see your husband or wife who you greatly love him/her with another person in bed?
can You smile?
Smile?
No, I would leave silent if she did not already find out I was home, and then call from the cell phone and tell her I am coming back home.
Later, back home, when the lover has left, I will tell her I saw them.
But in reality, I would have called on the cell phone already when I got to know my flight was cancelled, so chance is I will never see anything like that
