Only a person who begs constantly calls people stingy regularly. Because the only way you can know if people are stingy is by asking them for things you do not deserve. So, by calling others stingy, you are automatically calling yourself a greedy beggar who wants to reap where they have not sown. Begging is not a job. It is a vice. Go and work, and you will know why people are stingy with their money.
