Read this article to discover for yourself what the imperative mode of management is. Have no doubt that the imperative mode gives subtle suggestions, such as, "Perhaps you should improve the quality of your work or one of my superiors may demand that I fire you." See below for more facts about the imperative.
Use the imperative like this
Follow closely or you will look like an idiot to your friends. Next time a culprit, say, pokes you in the eye, tell them, "I really can't appreciate damage to my corneas." Rejoice in the fact that the concept of not poking as hard will at least cross their mind. Don't worry if you can't get it at first as even some of us make mistakes. Remember to be polite to your aggressor, and assert your position courteously.
Contrast with the exclamatory
To make an exclamation, simply append an exclamation mark to any sentence, e.g. "Where is my notebook!" Pronounce this sentence by downtalking, i.e. say the last at a lower pitch than the rest of the sentence. Feel free to place as many different punctuation marks after the exclamation point to achieve your effect, for example, "This is sentence.?!?,:';" Utter the latter with a chaotic up-down-up mood that leaves everyone crazy.
Practise not being bossy
Consider using the imperative when you want to inform and not offend. Avoid being too direct unless you like a class action suit of peers in earshot being directed at yourself. Instead opt for a tactful description such as, "Get the harmonica out of the kitchen, gizzle!" If you offend anyone, run away before they punch you in the thorax. Goad yourself for bossing people around until you learn.
Fit in with the crowd
Tuck your head into your shell if you feel the least bit of an urge to get preachy. Move the discussion to something less offensive, conform to what others think you should do, and never criticise the sitting prime minister.
