You reap what you sow. For example, if you plant a seed of corn, you will not get spinach; You will get corn. If you plant an apple seed, you will get an apple tree. It’s a principle at work. If you smile at someone, he is most likely to smile back. If you offer forgiveness, people are more likely to forgive you. If you treat your wife with love, respect, generosity (and help out around the house), you’ll likely reap more loving affection. But if you’re harsh, cheap and lazy, you’re going to reap trouble.
