I take a long walk every day, and, whenever I saw this man, I would wave to him. He would just frown at me and look away. Even so, I would always wave and think kindly of him, sending him metta. I was not phased by his attitude; I never gave up on him. Whenever I saw him, I waved. After about a year, his behavior changed. He stopped frowning. I felt wonderful. The practice of loving friendliness was beginning to bear fruit.
After another year, when I passed him on my walk, something miraculous happened. He drove past me and lifted one finger off the steering wheel. Again, I thought, “Oh, this is wonderful! Loving friendliness is working.” And yet another year passed as, day after day, I would wave to him and wish him well. The third year, he lifted two fingers in my direction. Then the next year, he lifted all four fingers off the wheel. More time passed. I was walking down the road as he turned into his driveway. He took his hand completely off the steering wheel, stuck it out the window, and waved back to me.
