The feeling of one who is displeased; irritation or uneasiness of the mind, occasioned by anything that counteracts desire or command, or which opposes justice or a sense of propriety; disapprobation; dislike; dissatisfaction; disfavor; indignation.
That which displeases; cause of irritation or annoyance; offense; injury.
Be careful how you do one man a pleasure which must needs occasion equal displeasure in another. For he who is thus slighted will not forget, but will think the offence to himself the greater in that another profits by it; while he who receives the pleasure will either not remember it, or will consider the favour done him less than it really was. Francesco Guicciardini
