Say This...Not That

I don't profess to be Miss Manners or anything, but I swear, some people need a primer on how to give compliments. I am here to provide a couple of suggestions.
1) A qualified compliment is probably not much of a compliment. Example: Say, "You are really smart." Not, "You are book smart." When you tell someone they are book smart, you are actually saying, you don't have the sense God gave a goose, but you can do math (or history, English, literature, etc.). In every other respect you are dumb as a box of rocks. 2) Avoid comparing the person to others. Example: Say, "You are looking good." Not, "Compared to Bertha, you are a twig." This tells the person, "Up until today, I had thought you were the fattest person on the planet. Now, unbelievably, I have found I am wrong. There is another person even fatter than you." 3) Avoid comparing others to someone/something which is obviously horrible. Example: Say, "Do you do something different with your hair?" Not, "Are you trying to look like Einstein with that 'do?" 4) Avoid using ambiguous words. Example: Say, "You have really good muscle tone." Not, "You're really solid." Is that even a compliment? What does it mean? 5) Avoid using words which are generally construed as uncomplimentary terms. Example: Say, "You have beautifully shaped calves." Not, "You have meaty calves." There is no part of a woman's body she wants referred to as meaty.
Basically, I think Thumper said it best in Bambi, "If you can't say nothin' nice, don't say nothin' at all."
