Drawing just one rune is the easiest and probably the most common method of reading. Without a storyline like when interpreting a layout, there are no runes to compare and contrast. Simply interpret the rune as the answer to the question.
Alternatively, this method may be used repeatedly in succession to allow the runes to tell a story.
This rune warns to tread lightly. There may be friction in relationships and unmet needs. Sometimes hard lessons are necessary in life. Some things we just don't want to learn. Be careful not to burn your bridges.
