There was a stammerer going on the bus. After a while, he asked a passenger:

- What....ti..me....is....is.....i...t?

The passenger didn’t respond, he just showed his watch to the stammerer.

A while later, still the same question, the passenger said nothing and did the same as the last question: he showed the stammerer his watch.

When the stammerer got off the bus, an old man said to the passenger:

- Why were you being so disrespectful to that man? You didn’t answer him properly.

He responded in return:

- Because I...I...a..m.....a..a.....stammer...er....too. If....f...I...I...had answered...ed...d.....him......, he.......would...d...d....ha..ve.....thought..t...t....me..e...making jokes....s..s...on.....him...

Husband’s mistake + Wife is correct = Husband’s mistake

Husband is correct + Wife is correct = Wife is more correct

Husband is correct + Wife’s mistake = “Why didn’t you tell me sooner? It’s all your fault” wife said

Husband’s mistake + Wife’s mistake = “You have to be responsible for our mistake” wife said
