This was illustrated in the present case.

Mortimer was frequently referred to in the presence of Flora, and praised in the highest terms; while the bare mention of Watson's name was sure to occasion a series of disparaging remarks.

The effect was just the opposite of what was intended.

The more her father said in favor of the thrifty young merchant, the stronger was the repugnance felt towards him by Flora; and the more he had to say against Watson, the better she liked him.
This went on until there came a formal application from Mortimer for the hand of Flora.

It was made to Mr.Johnson first, who replied to the young man that if he could win the maiden's favor, he had his full approval.
