Indirect is better than direct

There are quite a few cases that perhaps making an indirect approach is a better choice than being direct. An example of doing so would be if my mother were to ask me to go out with her when I'm really tired and just want nothing but my sleep. Instead of saying "I'm tired get out of my face" I might say something like "I'm not feeling well can we do this some other time?" This way I'm still getting what I want :)
