Terry Pratchett. The creators of spells (№ 339430)

Magicians of the lower grades are often called street magicians. In fact street magic is a very respectable and highly specialized form of magic that attracts silent, thoughtful people with Druidic beliefs and horticultural tendencies. If you invite a street magician to visit, he will spend half of the evening, whispering something in your potted plants. The other half parties it will hold, listening to their answers.
