Proverbs 27:14

He that blesseth his friend with a loud voice, rising early in the morning, it shall be counted a curse to him.

To pronounce a blessing upon a friend with a loud voice turns an intended kindness into an intrusive act. Pressing it upon him by rising early in the morning makes the timing itself unwelcome. What was meant as good will then be counted as a curse to the one who gives it rather than received as kindness.
