Never underestimate the power of symbolism and simplicity! If you don’t have any tools, go for a walk and try to pick a few flowers.
Draw a sigil or simply write both your names on a paper and put them in a jar. If you don’t have a jar, even a toilet paper tube will do!
Say: “Help us both have gratitude for the lessons we taught each other. Clear away any negative friction, bringing love and mutual appreciation.”
Bury the spell jar in fertile soil and walk away.
All the best!
