The husband assumes that his wife will pay the mortgage at the bank on time but her priority was different, she kept an appointment at the school with the children's teacher.

After all he is working overtime at his construction job and he does not have the time to do this. Later, when he gets a letter from from the bank stating that payment is overdue, conflict between the husband and wife can be the result.

When one person assumes something about another person, then getting a different result, this, can cause distress to the person who assumed that everything will be alright.

Now, the wife assumes her husband will remember their anniversary this year. After all, how can he forget that most important date, in their life?

A conflict can result when the husband not only doesn’t make plans to celebrate their special day but doesn’t even remember that it is their anniversary.
